Configuring IEEE 802.1Q and Layer 2 Protocol Tunneling

Configuring the SP Edge Switch

Command or Action

Example:

Purpose

is exceeded. If no protocol option is specified, the threshold applies to each of the tunneled Layer 2 protocol types. The range is 1 to 4096. The default is to have no threshold configured.

 

Switch(config-if)# l2protocol-tunnel

Note

If you also set a shutdown threshold on this interface, the

 

drop-threshold point-to-point pagp 500

 

 

 

drop-thresholdvalue must be less than or equal to the

 

 

 

shutdown-threshold value.

Step 7

no cdp enable

Disables CDP on the interface.

Example:

Switch(config-if)# no cdp enable

Step 8

spanning-tree bpdu filter enable

Enables BPDU filtering on the interface.

Example:

Switch(config-if)# spanning-tree bpdu filter enable

Step 9

exit

Returns to global configuration mode.

Example:

Switch(config-if)# exit

Step 10 errdisable recovery cause l2ptguard

Example:

Switch(config)# errdisable recovery cause l2ptguard

Step 11 l2protocol-tunnel cos value

Example:

Switch(config)# l2protocol-tunnel cos 2

(Optional) Configures the recovery mechanism from a Layer 2 maximum-rate error so that the interface is reenabled and can try again. Errdisable recovery is disabled by default; when enabled, the default time interval is 300 seconds.

(Optional) Configures the CoS value for all tunneled Layer 2 PDUs. The range is 0 to 7; the default is the default CoS value for the interface. If none is configured, the default is 5.

Step 12

end

Returns to privileged EXEC mode.

Example:

Switch(config)# end
