Setting the mode to classify means that subscriber and flow classification will use the VLAN tag.
Using VLAN classification is mutually exclusive with any IP tunnels.
Note that using The a-symmetric skip value incurs a performance penalty.
To configure the VLAN environment
Step 1 From the SCE 1000(config if)# prompt, type:
vlan [symmetric {classify|skip}] [a-symmetric skip]and press
Enter.
EXAMPLE:
The following example selects symmetric skip VLAN tunnel environment.
SCE 1000(config if)#vlan symmetric skip
Configuring the MPLS Environment
Use this command to set the MPLS environment. Use the VPN keyword when the labels are
mandatory in the traffic, otherwise use Traffic-Engineering (default).
Note that using the VPN value incurs a performance penalty.
To configure the MPLS environment
Step 1 From the SCE 1000(config if)# prompt, type:
mpls [vpn|Traffic-Engineering] skip and press Enter.
EXAMPLE:
The following example selects the VPN MPLS tunnel environment.
SCE 1000(config if)#mpls vpn skip
Configuring the L2TP Environment
Use this command to set the port number that the LNS and LAC use for L2TP tunnels. The
default port number is 1701.
To configure the L2TP port number
Step 1 From the SCE 1000(config if)# prompt, type:
L2TP identify-by port-number <number> and press Enter.
