The following problem has no workaround: 

■

Removing a port mirror causes an interface to stay in the 
“UP” state with no connections to the interface.

If you mirror multiple ports, the switch monitors both transmit and 
receive traffic regardless of the direction of traffic that you specify. 
The switch continues to monitor both directions of traffic even if 
you remove the port mirror with multiple source ports and set up a 
new port mirror with a single source port. 

Reset the switch before setting up a port mirror with a single source 
port. 

Version 5.2.2 of the switch software does not support piggyback 
ports on 80-series modules. If your switch is running a version 
earlier than 5.2.2 and you set up a port mirror with a piggyback port 
on an 80-series module and you then download 5.2.2, specify 5.2.2 
as the startup configuration, and reset the switch, the switch retains 
the port mirroring information and will reset repeatedly as long as 
the port mirror exists. 

Before downloading and running v5.2.2, remove port mirrors with 
piggyback ports on 80-series modules. 

The following problems have no workaround: 

■

When you try to mirror a blocked port, the Web Agent 
displays the port as forwarding, but it is blocked. When you 
remove the blocked port from being mirrored, you receive 
panic messages on the console. The problem does not 
interrupt traffic or cause any other problems in the network.

■

If a standby supervisor module installed in slot 2 has become 
the Active supervisor (CPU) due to a failover, the web agent 
shows the supervisor module in slot 1 as available for 
mirroring during a port mirroring operation. This is incorrect. 
This problem does not affect traffic running in the network.

* Note:  The Supervisor module should not be configured 

for port mirroring even if it displays as available for 
port mirroring.
