Description
If OSPF is enabled, you may receive an OSPF syslog message on the NBU
while the system is coming up. This occurs because OSPF checks for the
license, but the license information is not available until the stack is formed.
In a Nortel SNA setup, you may experience temporary loss of Nortel SNA
functionality when UDP forwarding has approached maximum capacity.
Workaround: Configure a filter on the port that connects to the SNAS (or
depending on your configuration, on the port connected to the switch that,
in turn, connects to the SNAS) to isolate Nortel SNA SSCP traffic received
by the CPU.
The CLI commands to configure a filter are the following:
• qos ip-element <element id> src-ip <ipaddr/mask>
• qos classifier <value> set-id <value> element-type ip element-id <value>
• qos action <value> update-1p <value>
• qos policy <value> port <portlist> clfr-type class clfr-id <value>
in-profile-action <action id> prec <value>
When you simultaneously reset two or more non-adjacent stack members
causing other members to be isolated from the stack, the stack may fail the
DB exchange when the reset units attempt to re-join the stack.
Workaround: Reset the base unit, or change the ports status for a stack
(down/up).
MLT/Mac-sec: Traffic does not recover after reboot on a MLT with mac-sec
enable until you reboot the standalone.
To upgrade the SSH from Rel. 4.x.x to Rel. 5.1, you must first upgrade to 5.0.
Use the following procedure to upgrade from Rel. 4.x.x to Rel. 5.1.
1. Upgrade the agent image from Rel. 4.xx to Rel. 5.0
2. Upgrade the diag. image to Rel. 5.0.0.4 (this diag. image was released
with agent Rel. 5.1)
3. Upgrade the agent image from Rel. 5.0 to Rel. 5.1.
If a MAC is not present in the MAC-db at the SNAS, it is learned on a switch
port and entered as a dynamic PC into the NSNA client list. Adding the same
MAC to the MAC-db after that will not authenticate the MAC. The port will
need to be reset or NSNA disabled and enabled at the port to remove it from
the client list for subsequent authentication of that MAC.
NSNA dynamic ports must have Spanning Tree Learning mode Fast Learning
or Disabled when NSNA is globally enabled. STP Normal Learning mode will
not be restored if NSNA is disabled.
Adding or deleting host routes for hosts directly attached to the router in
non-backbone area is not advertised by the router without disabling and
enabling OSPF on the switch.
