• Only one guest VLAN is allowed per 802.1x port.
• The VLAN ID specified must already exist in the switch configuration. Use the 
vlan
 command to 
create a VLAN before configuring it as an 802.1x guest VLAN.
• If a guest VLAN is already configured for the specified 802.1x port when the 802.1x guest-vlan 
command is used, the existing VLAN ID is overwritten with the new value. 
Configuring the Supplicant Polling Retry Count
To configure the number of times the switch polls an unknown device connected to an 802.1x port, use the 
 command. For example,
-> 802.1x 3/1 supp-polling retry 10
If after the number of polling attempts specified the device has not responded with EAP frames, then the 
device is learned as a non-802.1x supplicant in a guest VLAN. If a guest VLAN was not configured for 
the 802.1x port, the device is blocked from accessing that port and no other attempts are made to solicit 
EAP frames from the device. 
Note that the polling interval is set to 0.5 seconds between each retry and is not a configurable at this time.

New Section, page 2-29
The following section should be added to page 2-29:
Configuring a BGP Peer with the Loopback0 Interface
Loopback0 is the name assigned to an IP interface to identify a consistent address for network manage-
ment purposes. The Loopback0 interface is not bound to any VLAN, so it will always remain operation-
ally active. This differs from other IP interfaces in that if there are no active ports in the VLAN, all IP 
interface associated with that VLAN are not active. In addition, the Loopback0 interface provides a unique 
IP address for the switch that is easily identifiable to network management applications.
It is possible to create BGP peers using the Loopback0 IP interface address of the peering router and bind-
ing the source (i.e., outgoing IP interface for the TCP connection) to its own configured Loopback0 inter-
face. The Loopback0 IP interface address can be used for both Internal and External BGP peer sessions. 
For EBGP sessions, if the External peer router is multiple hops away, the ebgp-multihop parameter may 
need to be used.
