Caveats
• CSCta77490
Symptom: When the type of a pVLAN is toggled from being a regular VLAN to a pVLAN and back
to regular VLAN in very small interval of time, the type change fails.
Workaround: Issue the type change commands with a 5 seconds gap in between.
• CSCtb34546
Symptom: When a PACL with deny ip any any is applied on mgmt0, CFS discovery gets stuck.
ip access-list ip1
10 deny ip any any
Applying such a ACL on the mgmt0
int mgmt 0
ip access-group ip1 in
would cause this issue.
Workaround: Remove the deny ip any any rule from the PACL applied on mgmt0 interface.
• CSCtb61197
Symptom: When a port channel provisioning fails because the system has reached the limit of
number of port channels supported, output of show san-portchannel continues to display the port
channel as present but down. The port channel is seen as down even if the member interface is
operationally up because it could not be provisioned correctly due to resource limitation.
Workaround: None.
• CSCtc44231
Symptom: LACP port channel doesn't come up. A VLAN is deleted from the switch which is also
configured as native VLAN for the lacp port channel.
Workaround: Create the VLAN or remove the native VLAN config from the lacp port channel.
• CSCtc77180
Symptom: Ports are error disabled with error Ethernet interface not present if feature fcoe is
enabled immediately after the switch prompt comes up on bootup.
Workaround: Enable feature fcoe after confirming that the interfaces are displayed in the output
of show interface brief.
• CSCtb58641
Symptom: If a mac-address moves from an isolated host port to a promiscuous trunk port, in certain
conditions, the mac-address is never cleared from the system.
Workaround: None
• CSCtc36397
Symptom: Changing the role-priority and flapping the peer-link does not change the roles of
the vPC peers. This happens when one of the switch has its role as Operational primary due
to an earlier reload of the primary switch.
Workaround: None
• CSCtb84512
Symptom: In mixed span mode where ethernet port channel, vfc and FC ports are span sources and
ethernet interface is a span destination, vfc flap causes the traffic coming in on ethernet port channel
to be not spanned.
Workaround: Remove and add span source command for the ethernet port channel.
