Firmware Version 3.2.0 Beta 11
Applies to PTMP equipment: C6x and C5 series in PtMP mode with A6 only.
NOTE: This firmware version makes C5X like C5C radios compatible with A6 radios as CPE in a PtMP configuration. They can only work as clients, so to make them PTP, we need to reset them to factory defaults and load the correct firmware.
PTMP - Issues Resolved
When configuring an SSID with a name containing 32 characters including special characters, it may cause the A6 device to restart every 15 minutes.
Improvements in KPI metrics reported through MMP (Mimosa Management Platform).
Improvements in VLAN and QoS configuration to ensure data traffic is not interrupted during client association events.
A6/C6x - Known PTMP Issues
In certain scenarios, the A6 WebUI may show that all clients have disassociated. In such cases, configuration changes on A6 may not be applied correctly. It is recommended to restart the A6 or take steps to disassociate and reassociate all clients because of this. In certain scenarios, the link uptime displayed on the C6x dashboard page may be incorrect.
If the device name of C6x is changed, it may result in a new association with its associated access point.
In certain scenarios, the client list and wireless statistics pages of WebUI may not show information about clients. Restarting the A6 can resolve this issue.
Firmware Version 3.2.0 Beta 10
Applies to PTMP equipment: C6x and C5 series in PtMP mode with A6.
New Features
Automatic Transmit Power Control
The transmission power for the uplink can be automatically adjusted to optimize link quality.
Speed Limitation
Data traffic on a C6x can be speed-limited in the uplink or downlink direction. Rate limit values can range from 0 to 1000 Mbps. When a speed limit of 0 Mbps is configured, effectively all data traffic is blocked from passing through the C6x in the configured direction.
Compatibility with 1 Gbps SFP Transceiver
A6 SFP ports now support 1 Gbps transceivers. Mimosa has qualified the following SFP media converters for use with the fiber port:
Avago AFBR-5710APZ, 850 nm multimode IEEE 802.3 Gigabit Ethernet (1.25 GBd) - 1000Base-SX
Avago AFBR-5715ALZ, 850 nm multimode IEEE 802.3 Gigabit Ethernet (1.25 GBd) - 1000Base-SX
Finisar FTLF8519P3BTL 850 nm multimode Gigabit Ethernet (1.25 GBd) - 1000Base-SX

Firmware Version 3.2.0 Beta 9
(Please note that C5x and C5c are NOT compatible with this version)
(Note: This beta firmware version is NOT compatible with MMP 1.3.0 BETA-3)
Firmware Version 3.2.0 Beta 7
Applies to PTMP equipment: C6x, C5X, and C5C
PTMP – New Features
5 MHz Channelization
Channel selection is now available in 5 MHz increments. This provides the ability to place the access point on non-standard Wi-Fi channels. When switching to previous beta versions, ensure this feature is disabled and standard wireless channels are selected.
Improvements in Channel Switching
When switching from one DFS channel to another DFS channel, client reassociation time has been reduced to approximately one minute. Client association is not affected by any channel changes if the primary channel remains unchanged. The device will automatically select the Wireless Protocol: 802.11ac or 802.11ax based on client capabilities.
PTMP – Issues Resolved
The system time obtained by C6x from A6 may have a delay of up to 7 minutes.
A6/C6x: Known PTMP Issues
Certain primary channels (Channel 258) are not compatible with A6/C6x even though WebUI may allow their selection.
The Site Survey page in C6x WebUI may display incorrect central frequency and primary channel for certain SSIDs broadcasted by A6 operating on non-IEEE channels.
It may not be possible to select the entire available bandwidth on the bandwidth test page in WebUI in certain scenarios.
The Client List page in A6 WebUI may become slow when there are more than eight associated clients.
C5x associations have stability issues when associated with A6.
1G SFP transceivers are not compatible with A6 SFP ports.
Firmware Version 3.2.0 Beta 6
Applies to PTMP equipment: C6x, C5X, and C5C
PTMP – New Features
A6 Device Name (NEID) in Beacon
A6 broadcasts its device name in wireless beacons.
New (3rd) 160 MHz Channel for India and United States
A6-C6x can operate on a new 160 MHz channel (5715 ~ 5875 MHz) when unlocked for India or the United States.
System Time for C6x from A6
C6x can obtain system time from A6 when they are associated and A6 has a good GPS signal.
SNMP
A6/C6x devices support read-only MIB accessible via SNMPv1, v2c, and v3. SNMP traps are also supported.
Alarms
A6/C6x devices support system notifications and threshold alarms. Alarm thresholds can be configured for temperature, GPS signal strength, SNR (Signal-to-Noise Ratio), PER (Packet Error Rate), RSSI (Received Signal Strength Indication), and PHY transmission rate. These notifications and alarms can be sent to a configured SNMP trap server.
MAC Address Forwarding Table
A6/C6x devices support viewing the L2 forwarding table learned by them. This table contains the MAC address of each learned host (behind a PTMP device), VLAN, and input port.
IPv6 DHCP-18/37 Option
The DHCPv6 Option-18/37 feature allows A6 to insert interface-id (option-18) and/or remote-id (option-37) for DHCPv6 requests or renewals coming from hosts connected to A6 clients. The following options are supported for Interface ID/Remote ID fields: - AP Device Name - AP MAC Address - Client MAC Address - Custom String (1 to 64 characters in length) - AP Device Name concatenated with Client MAC Address: AP Device Name, with Client Device Name and Client Host MAC Address, separated by configurable delimiters - #, /, :, or - - Custom String, AP Device Name, and Client Host MAC Address, separated by configurable delimiters - # , /, :, or -
Improvements in Diagnostic Tests
Ping and Traceroute tests now take additional parameters:
- Packet count, packet size, IPv6, and management interface for ping test.
- Maximum number of hosts and management interface for traceroute test.
Traceroute and Ping will accept URLs as destinations.
Q-in-Q Support
Each C6x client, associated with an A6, can be configured to add/insert a VLAN header/tag to all incoming data traffic, either untagged or tagged, on its Ethernet port to be forwarded to the A6 (for subsequent forwarding to the A6 Ethernet port). Note: the VLAN tag inserted TPID must be 0x8100. Traffic with VLAN tags containing management VLANs or VLAN ID configured in the pass-through list is excluded from this VLAN header insertion. The inserted VLAN tag must be removed from the traffic exiting the C6x Ethernet port. A separate VLAN policy can be applied to the A6 SSID, which applies to data traffic from all clients associated with that SSID.
Management VLAN
Devices can be configured with a separate VLAN solely for management access. A6 and its associated clients can be configured with separate VLANs.
IPv4 DHCP Option 82
The DHCP Option 82 feature provides controls to configure the access point (AP) as a DHCP relay agent, providing additional security by assigning one or more IP addresses to downstream devices that may not be trusted. The AP can be configured to insert circuit ID and/or remote ID for DHCP requests or renewals coming from hosts connected to A6 clients. The following options are supported for Circuit ID/Remote ID fields:
- AP Device Name
- AP MAC Address
- Client MAC Address
- Custom String (1 to 64 characters in length)
- AP Device Name concatenated with Client MAC Address: AP Device Name, with Client Device Name and Client Host MAC Address, separated by configurable delimiters - #, /, :, or –
- Custom String, AP Device Name, and Client Host MAC Address, separated by configurable delimiters - # , /, :, or -
DHCPv6
A6 and C6x devices can be assigned an IPv6 address via DHCPv6. This feature can be enabled/disabled via WebUI.
C6x Pointing
C6x WebUI supports a new "Pointing" page. This helps to aim/orient the C6x towards A6 for optimal performance. RSSI values on the pointing page are updated more frequently for more accurate pointing.
Pass-through VLAN
The Pass-through VLAN feature configures the radio to pass tagged traffic "as-is" if the VLAN ID is in the "pass-through list".
PTMP – Issues Resolved
In certain scenarios, executing site inspection may not yield any results.
The IAID field of DHCPv6 packets originating from a specific A6 or C6x device may not have the same value in all requests.
Disassociated clients cannot be removed from the client list.
In certain scenarios, A6 WebUI may report the client as disassociated even when the client is associated. Refer to the C6x WebUI dashboard for the correct association status.
Occasionally, client VLAN configuration may not be applied correctly to clients.
Occasionally, Client Status may be displayed as "Default" regardless of its configuration, even if the client has "Client Data VLAN" configuration applied.
WebUI may become slow under certain conditions. A device restart may be the only way to recover it.
C6x pointing mode may not work.
Running a bandwidth test with maximum offered load may cause wireless link traffic to stop. Only a device restart can resolve this issue.
VLAN IDs cannot be configured as a range in the pass-through VLAN list.
Clients configured with VLAN and connected to C6x Ethernet may not receive an IP address via DHCP or DHCPv6 if the client's VLAN is inserted through A6-C6x and DHCP options are enabled.
Ethernet packets with frame sizes greater than 1522 are dropped from the C6x Ethernet port.
After firmware upgrade or restart via WebUI, the countdown timer shows 600 seconds. However, devices complete their restart in 300 seconds.
Deleting all IP addresses on the Static IP Address page and disabling DHCP will render the device inaccessible.
C6x may lose the default IPv6 route learned from router advertisements in the C6x management VLAN.
PTMP - Known Issues A6/C6x - PTMP
If the total number of configured management IP addresses on the device exceeds 8, a new IP address may not be configured. - Enterprise SSID security type is currently not supported.
On the Wireless Statistics (link) page, MU statistics may not populate.
After changing settings on WebUI pages, the user may need to refresh the page to see the applied configuration.
Occasionally, some pages may be temporarily incorrect or out of sync (e.g., GPS may not display correctly on Dashboard or Location page).
A6 dashboard may have empty wireless details.
Factory initial configuration does not have a DNS server configured. Configure DNS server settings to resolve all applicable domain names (such as NTP server).
The device will only send valid statistics to MMP/NMS as long as the radio is configured with the current time via NTP or GPS.
Some help text descriptions may be outdated. Contact Mimosa support for more details.
When upgrading firmware, the load percentage may not reach 100% before the countdown starts.
User management may fail when attempting to delete a user who has logged in but is still deleted as requested.
Occasionally, the dashboard graph may update less frequently than every 5 seconds under heavy load.
Occasionally, the dashboard may not display the correct central frequency, primary channel, and bandwidth.
The user interface does not provide a warning that read-only users cannot run spectrum analysis or site survey.
Changing the operational bandwidth will cause clients to disassociate and then reassociate.
Independent browser sessions allow simultaneous Spectrum Analysis and Site Inspection, possibly yielding incorrect results.
When removing the management VLAN, the IP address assigned to the management VLAN interface may not be cleanly removed. WebUI will prevent the user from reusing this subnet.
If the C6x host Ethernet port has a 100 Mbps capacity, then the C6x Ethernet port may only negotiate at 100 Mbps/half-duplex.
Configuring a protocol ID of 0x88A8 may not result in VLAN header insertion.
Configuring SSID-VLAN may not result in VLAN tag insertion in certain scenarios.
WebUI allows configuring IP addresses belonging to the same subnet on management VLAN and non-management VLAN interfaces. Users should refrain from doing so.
When multiple SSIDs are configured, accessing the C6x WebUI may not be possible. The network may see duplicate packets when attempting to reach C6x.
The system time obtained by C6x from A6 may have a delay of up to 7 minutes.
