Bug ID

Description

CSCwb90675

If a EOR gets stuck while configuring monitor scale at flow system configuration, try the following workaround:

-       Save current running config to bootflash, other local file system or USB.

-       Reload ascii

-       Reload switch.

-       Do a SUP system switchover (SSO).

CSCwe74517

When you remove template peer-policy under l2vpn EVPN address-family it deletes the prefixes. The workaround is to reconfigure the affected neighbor or restart BGP.

CSCwh49061

VLAN Mapping: strict incompatibility during downgrade from 10.3.x to 9.3.x.
VLAN Mapping commands need to be removed when you downgrade from 10.3.x to 9.3.x versions. Workaround is to remove switchport vlan mapping command and add it again after the downgrade.

CSCwi99525

aFor specific fan speeds see the Overview section of the Hardware Installation Guide.

b This switch runs with +1 redundancy mode so that if one fan fails, the switch can sustain operation. But if a second fan fails, this switch is not designed to sustain operation. Hence before waiting for the major threshold temperature to be hit, the switch will power down due to entering the fan policy trigger command.
