Cambium Networks ePMP 1000 Software Release 2.6.2
System Release 2.6.2 is a maintenance release and includes the following:
Enhancements:
- Support for Hidden SSID on the SM in Standard WiFi mode. SM will probe for SSIDs in its Preferred AP List.
- TFTP recovery for radios that are rendered inoperable due to flash corruption (typically caused by power interruption during a software upgrade).
- Please see this Knowledge Base post for the recovery procedure.
Defect Fixes:
- TX power notification appears on the GUI notifications drop down repeatedly when ACS is enabled.
- Open SRS vulnerability. Port 53 is not blocked when Separate Management IP is enabled.
- Enabling WLAN Deny Layer 2 firewall causes the radio to not be accessible in Spectrum Analyzer mode.
- On a 40 MHz channel, the AP may crash with the signature “ _ieee80211_free_node+0xcc/0x334 [tdd_umac]' under heavy traffic.
- Management interface may respond slowly or stop responding to CLI commands, when “config show" command is issued repeatedly within an interval of few minutes.
- When radar is detected and the radio enters a 30 minute NOP period, a subsequent radar hit resets the 30 minutes NOP timer, prolonging it beyond 30 minutes.
- In 5.9 GHz band ePTP mode, Slave does not register to Master in Release 2.6 and later.
- When SM obtains its VLAN configuration through RADIUS, it is not reachable on its management interface through its WLAN.
- RADIUS authentication request not sent to alternate RADIUS servers upon failure to reach primary RADIUS server.
- Force 180s running as ePTP Master and Slave may crash after several hours of continuous, overloaded traffic through the link.
- cnMaestro™ related fixes:
- GUI user logged out when ePMP is on-boarded to cnMaestro™
- Under high traffic load, cnMaestro™ reports SM(s) as offline even though they are registered to the AP and passing user traffic.
- 2.4 GHz Force 200 displays as 5 GHz Force 200
- Incorrect cnMaestro™ Remote Management Status shown on SM's Dashboard when AP is on-boarded.
Внимание
ePMP radios running System Release 2.1 or earlier cannot be directly upgraded to System Release 2.6.2. Please upgrade to System Release 2.6 first, then upgrade to System Release 2.6.2. Stepping through System Release 2.6 is not required if the ePMP radio is running System Release 2.2 or later.

|---|---|
| 11156 | On rare occasion, AP would detect a false radar hit on a DFS channel and stop transmission or move to an alternate channel (if configured). (Resolved in 2.6.1) |
| 11033 | On rare occasion when the AP is in TDD mode, upon an SM disassociation from the AP, the AP may crash due to incorrect data handling regarding the SM.

An issue related to DDR (memory) timing was exposed under cold ambient temperatures (below -5°C). This issue impacts only a specific set of MAC addresses that were manufactured. However, this issue is resolved by adjusting the timing of the DDR in software for stable operation, in all temperatures for which ePMP is rated for. (Resolved in 2.6.1) |
