7.18.1 mpls
This command sets the MPLS characteristics for an uplink port. Use the no form
to restore the default values.
Syntax
mpls {l2 | tunnel <tunnel-label> | vc <vc-label> |
next-hop <ip-address>}
no mpls {l2 | tunnel | vc | next-hop}
• l2 - Configures a port to enter L2MPLS uplink port mode.
Ports 1 - 27 can be configured as L2MPLS ports.
• tunnel-label - Sets the MPLS tunnel label that will be used to
construct the MPLS header on the L2MPLS uplink port. This label
is used by switches within the MPLS core network to establish a
path from the entry point to the exit point. (Range: 0-1048574)
• vc-label - Sets the MPLS port-based virtual channel (VC) label.
All incoming packets forwarded to MPLS ports will use this VC to
generate the MPLS label. The VC is used to map traffic to a specific
customer port on the edge switches at the boundaries of the MPLS
network. (Range: 0-1048574)
• ip-address - Configures the next hop MPLS switch/router IP
address. This IP address will be used to identify the next hop across
the MPLS network or, more commonly, the edge switch where traffic
is passed on to the customer.
Default Setting
• no mpls l2 uplink port mode
• no mpls tunnel label
• no mpls vc label
• no mpls next-hop
