Software Fixes in Release M.08.51 - M.10.72
Release M.10.72
Config (PR_0000005002) — If a friendly port name uses the characters TRUNK=, then
■
after a reload, all the trunking configuration will have been removed from the configuration.
GVRP (PR_0000012224) — Changing the GVRP unknown-vlan state from 'block' to 'learn'
■
and vice versa stops all GVRP advertisements from that interface until the interface is
disabled and then re-enabled.
■ RADIUS Accounting (PR_0000012487/0000037453) — The switch doesn't send an
accounting-stop when a switch reload closes the session.
■ Meshing/STP (PR_0000004611) — Concurrent use of meshing and spanning tree on 10-
GbE-CX4 ports may result in instability in spanning tree, with chronic root bridge transitions
every 20 to 40 seconds.
■ SNMP (PR_0000017534) — SNMP communication may cease after a software update and
configuration copy to the switch.
DHCP-Snooping/IP Lockdown (PR_0000013457) — DHCP-Snooping does not block
■
DHCP offers from an untrusted port as it should when the feature is configured in combina-
tion with IP source lockdown.
Authentication (PR_0000014177) — The switch consumes too many packets during the
■
AAA Authentication and dynamic VLAN assignment, potentially causing clients that require
bootP to fail to retrieve their configurations and initialize.
Authentication (PR_0000011138) — If the RADIUS server becomes unavailable, the eap-
■
radius authorized option allows the switch to authenticate devices. If the response time of the
RADIUS subsystem is greater than the server-timeout value on the switch or the device
supplicant then switch will not be able to authenticate devices, and no warning of this failure
will be displayed. This fix triggers the display of the following CLI message.
The RADIUS connection timeout must be less than the authentication
server timeout for the switch to authenticate automatically when the
RADIUS server is unavailable.
■ DHCP-Snooping (PR_0000012237) — The DHCP-Snooping binding table has incorrect
lease times when the binding table has been read at boot.
DHCP-Snooping (PR_0000018615) — DHCP-Snooping may not block appropriately on
■
untrusted ports.
RADIUS Accounting (PR_0000017732) — RADIUS accounting is incrementing the
■
wrong counter in response to a dropped (invalid) packet from the RADIUS server.
DHCP-Snooping (PR_0000018613) — When a DHCP client is unable to access the
■
network due to receipt of a DHCP-NACK (expected and desired behavior in that circum-
stance), there is no indication of why the 'failure' is occurring to help the network adminis-
trator understand what is happening. This fix adds log messages similar to the following.
