Configuring ISL for VLAN Routing
Cisco AS5300 Universal Access Server Software Configuration Guide 3-48
Note the following information for Serial 0:23 (the first half of the messages):
— Layer 1 Status should be “DEACTIVATED.”
— Layer 2 Status should be “TEI_ASSIGNED.” (It might take several seconds for Layer 2
status to appear.)
— Layer 3 Status should be “0 Active Layer 3 Call(s).”
The second half of the messages display information for Serial 1:23.
Tips
If you are having trouble:
•
Make sure the cable connection is not loose or disconnected if the Layer 1 Status is
“Deactivated.” This status message indicates a problem at the physical layer.
•
There may be a problem with your telco or the framing and line code types you entered may not
match your telco’s. A Layer 2 error indicates that the access server cannot communicate with the
telco; there is a problem at the data link layer.
Configuring ISL for VLAN Routing
Use the Inter-Switch Link (ISL) to connect multiple Virtual LANs (VLANs) using the Ethernet
Media Access Control (MAC) and Ethernet media.
