set interface l2 tag-rewrite

Summary/usage

set interface l2 tag-rewrite <interface> [disable | pop {1|2} | push {dot1q|dot1ad} <tag> <tag>].

Description

VLAN tag rewrite provides the ability to change the VLAN tags on a packet. Existing tags can be popped, new tags can be pushed, and existing tags can be swapped with new tags. The rewrite feature is attached to a subinterface as input and output operations. The input operation is explicitly configured. The output operation is the symmetric opposite and is automatically derived from the input operation.

POP: For pop operations, the subinterface encapsulation (the vlan tags specified when it was created) must have at least the number of popped tags. e.g. the "pop 2" operation would be rejected on a single-vlan interface. The output tag-rewrite operation for pops is to push the specified number of vlan tags onto the packet. The pushed tag values are the ones in the subinterface encapsulation.

PUSH: For push operations, the ethertype is also specified. The output tag-rewrite operation for pushes is to pop the same number of tags off the packet. If the packet doesn't have enough tags it is dropped.

Example usage

By default a subinterface has no tag-rewrite. To return a subinterface to this state use:

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 disable

To pop vlan tags off packets received from a subinterface, use:

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 1

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 2

To push one or two vlan tags onto packets received from an interface, use:

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1q 100

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1ad 100 150

Tags can also be translated, which is basically a combination of a pop and push.

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-1 dot1ad 100

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-2 dot1ad 100 150

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-2 dot1q 100

vpp# set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-1 dot1q 100 150

vpp# show bridge-domain 200 detail

test l2fib

Summary/usage

test l2fib [add|del|check] mac <base-addr> count <nn>.

Description

The set of 'test l2fib' commands allow the L2 FIB table of the default bridge domain (bridge-domain-id of 0) to be modified.

Example usage

Example of how to add a set of 4 sequential MAC Address entries to L2 FIB table of the default bridge-domain:

vpp# test l2fib add mac 52:54:00:53:00:00 count 4

Show the set of 4 sequential MAC Address entries that were added:

vpp# show l2fib verbose

4 l2fib entries

Example of how to check that the set of 4 sequential MAC Address entries were added to L2 FIB table of the default bridge-domain. Used a count of 5 to produce an error:

vpp# test l2fib check mac 52:54:00:53:00:00 count 5

The output of the check command is in the log files. Log file location may vary based on your OS and Version:

# tail -f /var/log/messages | grep l2fib_test_command_fn

Example of how to delete a set of 4 sequential MAC Address entries from L2 FIB table of the default bridge-domain:

vpp# test l2fib del mac 52:54:00:53:00:00 count 4

Declaration and implementation

Declaration: l2fib_test_command (vnet/vnet/l2/l2_fib.c line 599)

Implementation: l2fib_test_command_fn.

Summary/usage

test l2patch rx <intfc> tx <intfc> [del].

Description

Example usage

vpp# test l2patch rx <intfc> tx <intfc> [del]

Todo:: This is incomplete. This needs a detailed description and a practical example.

Declaration and implementation

Declaration: test_patch_command (vnet/vnet/l2/l2_patch.c line 374)

Implementation: test_patch_command_fn.
