• Skip MPLS headers.
The MPLS environment is assumed to be Traffic-Engineering.
• No IP-tunnel support – L2TP tunnels will not be skipped and therefore all flows within a
single L2TP tunnel will be classified as the same flow.
Selecting the Tunneling Mode
Use these commands to configure tunneling:
• ip tunnel
• vlan
• mpls
• L2PT identify-by
Configuring IP Tunnels
By default, IP tunnel recognition is disabled. Use this command to configure recognition of L2TP
tunnels and skipping into the internal IP packet.
An IP tunnel is mutually exclusive with using VLAN for classification.
To configure IP tunnels:
Step 1 From the SCE 1000(config if)# prompt, type:
ip tunnel L2TP skip and press Enter.
To disable identification of IP tunnels:
Step 1 From the SCE 1000(config if)# prompt, type:
no ip tunnel and press Enter.
Configuring the VLAN Environment
Use this command to configure the VLAN environment. There are three options:
• symmetric classify
• symmetric skip (default)
• a-symmetric skip
