PowerConnect 6224/6224F/6224P/6248/6248P Release Notes Summary ISDP updates are not including Voice VLAN Reply TLV when Voice VLAN ID on interface is changed. PC6200 fails to reauthorize IP phone upon enabling and disabling Voice VLAN authentication. When Line or enable method is used as login method and enable authentication is none, the user is unable to enter into Privileged EXEC mode. Cannot change LAG mode from Static to Dynamic via CLI. User Impact Upon changing configuration immediately after getting the VLAN assigned, DUT stops advertising Voice VLAN reply TLV in its ISDP updates which causes IP phone to change its VLAN properties. Once a phone is configured, enable Voice VLAN authentication, wait for DHCP discovery again, and then disable Voice VLAN authorization. On disabling Voice VLAN authorization, PC6200 fails to authorize IP phone based on the received LLDP packet (with network policy TLV). If login authentication method is Line or Enable, and enable authentication is None, you will always get read-only access (because there is no user configured for line or enable authentication). The user will never get read-write access. Cannot change LAG mode from Static to Dynamic via CLI. Workaround The administrator can work around this problem by shutting down the port and restarting it after the configuration is changed. Disconnect and reconnect the phone to the port, the phone gets authorized. If enable authorization is set to None, ensure that the login authorization method is at least TACACS, Radius, or Local. Any authentication method that requires a user configuration will ensure that the user will get proper access based on how the user is configured. The user may change the LACP Mode using the Graphical User Interface. System Firmware Version 3.2.0.6 Page 27
