2558 ExtremeWare 7.7 Command Reference Guide
MPLS Commands—BlackDiamond Switch Only
configure mpls vpls
config mpls vpls <vpls_name> {vman-id <vman_id>} {mtu <number>}
Description
Configures transmit parameters for packets received on the local VPLS interface as specified by
vpls_name.
Syntax Description
Default
Priority - 0
ttl_value - 4
number (MTU) - 1500
Usage Guidelines
This command optionally configures transmit parameters for packets received on the local VPLS
interface as specified by
vpls_name
.
By default, the
vman_id
is automatically chosen when the vpls is configured, but may be changed by
specifying the
vman-id
keyword. The
vman-id
parameter specifies the VLAN ID used internally in the
switch to identify the vpls port list configured for
vpls_name.
Valid values are 1 through 4096. The
specified
vman-id
cannot conflict with any other configured VLAN ID.
The
mtu
keyword optionally specifies the MTU value of the VPLS transport payload packet (customer
packet). The
mtu
value is exchanged with vpls configured peer nodes. All VPLS peer nodes must be
configured with the same
mtu
value. If the mtu values do not match, VC-LSPs cannot be established
between VPLS peers. By default the VPLS
mtu
is set to 1500. The configurable
mtu
range is 1492 through
9216. Changing the mtu setting will cause established VC-LSPs to terminate. VPLS payload packets may
be dropped if the VPLS MTU setting is greater than the MPLS MTU setting for the VC-LSP interface.
The vplsping command may be used to verify end-to-end path connectivity for specific payload packet
sizes (see VPLS Ping Command on page 3).
Example
None
History
This command was first available in an ExtremeWare 7.3.0.
vpls_name Identifies the VPLS within the switch (character string)
vman-id Specifies the VLAN ID used internally in the switch to identify the vpls port list configured for
vpls_name.
number Specifies the MTU value of the VPLS transport payload packet.
