VLANs operate according to specific configuration rules. When creating VLANs, 
consider the following rules that determine how the configured VLAN reacts in 
any network topology:

•

All ports that are involved in port mirroring must have memberships in the 
same VLANs. If a port is configured for port mirroring, the port’s VLAN 
membership cannot be changed.

•

If a port is a trunk group member, all trunk members are added or deleted 
from the VLAN.

•

All ports involved in trunking and port mirroring must have the same VLAN 
configuration. If a port is on a trunk with a mirroring port, the VLAN 
configuration cannot be changed.

•

Auto PVID can be activated by creating a VLAN and enabling Auto PVID for 
it.

For more information about configuring VLANs, see

MultiLink Trunks allow you to group from two to four switch ports together to 
form a link to another switch or server, thus increasing aggregate throughput of 
the interconnection between the devices (up to 800 Mb/s in full-duplex mode). 
You can configure up to six MultiLink Trunks. The trunk members can only reside 
on a single unit. MultiLink Trunking software detects misconfigured (or broken) 
trunk links and redirects traffic on the misconfigured or broken trunk link to other 
trunk members within that trunk.

You can use the Trunk Configuration screen to create switch-to-switch and 
switch-to-server MultiLink Trunk links (

 and 

).

 shows two trunks (T1 and T2) connecting Switch S1 to switches S2 

and  S3.
