Detailed Description

Ethernet VLAN Tag Rewrite.

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.

int_l2_pbb_vtr()

static clib_error_t* int_l2_pbb_vtr ( vlib_main_t *  vm, unformat_input_t *  input, vlib_cli_command_t *  cmd  )

static

Set subinterface pbb vtr enable/disable.

The CLI format is: set interface l2 pbb-tag-rewrite <interface> [disable | pop | push | translate_pbb_stag <outer_tag> dmac <address> smac <address> s_id <nn> [b_vlanid <nn>]]

Set subinterface vtr enable/disable.

The CLI format is: set interface l2 tag-rewrite <interface> [disable | pop 1 | pop 2 | push {dot1q|dot1ad} <tag> [<tag>]]

"push" can also be replaced by "translate-{1|2}-{1|2}"
