Chapter 21 Configuring Pseudowire

Configuring Pseudowire

	Command		Purpose
Step 4	encapsulation udp		Specifies the UDP transport protocol.
	Example:
	Router(config-pw-class)#
	encapsulation udp
Step 5	ip local interface loopback		Configures the IP address of the provider edge (PE) router interface as the
	interface-number		source IP address for sending tunneled packets.
	Example:
	Router(config-pw-class)# ip local
	interface Loopback 1
Step 6	ip tos value value-number		Specifies the type of service (ToS) level for IP traffic in the pseudowire.
	Example:
	Router(config-pw-class)# ip tos
	value 100
Step 7	ip ttl number		Specifies a value for the time-to-live (TTL) byte in the IP headers of Layer
			2 tunneled packets.
	Example:
	Router(config-pw-class)# ip ttl 100
Step 8	controller {e1t1} slot/port		Enters E1/T1 controller configuration mode.
	Example:
	Router(config)# controller [e1t1]
	0/0
Step 9	cem-group group-numberunframed		Assigns channels on the T1 or E1 circuit to the CEM channel. This
			example uses the unframed parameter to assign all the T1 timeslots to the
	Example:		CEM channel.
	Router(config-controller)#
	cem-group 4 unframed
Step 10	exit		Exits controller configuration.
	Example:
	Router(config-controller)# exit
Step 11	interface cem slot/port		Selects the CEM interface where the CEM circuit (group) is located
			(where slot/subslot is the SPA slot and subslot and port is the SPA port
	Example:		where the interface exists).
	Router(config)# interface CEM0/4
Step 12	no ip address		Disables the IP address configuration for the physical layer interface.
	Example:
	Router(config)# no ip address
Step 13	cem group-number		Defines a CEM channel.
	Example:
	Router(config-if)# cem 4
