bytes in hex format. The specified or learned MAC address is copied into the destination MAC address
field of the VPLS echo request and is included in the L2-VPN Prefix Target FEC TLV. By default, the
switch's MAC address is used for the source MAC address of the VPLS echo request. The
optionally specifies the source MAC address used for the VPLS echo request. This option allows the
VPLS echo request to be sent as if it originated from a customer's source MAC address. If link
aggregation is supported along the path to the destination MAC address, this insures that the VPLS
"ping" verifies connectivity through the VPLS network for the exact same path that the customer's traffic
would travel.
The optional

The optional size keyword specifies the number of bytes to include as payload data in the VPLS ping
packet. If no
minimum valid
the type of VPLS ping packet sent, but the total size of the VPLS ping packet cannot exceed the
configured jumbo packet size, if jumbo frames are enabled, or 1518 if jumbo frames are disabled. If the
parameter is specified, the size of the packet will increment by one byte for each new VPLS
end_size
echo request sent. The next VPLS echo request is not sent until the VPLS echo response for the previous
packet is received. This is useful for detecting interface MTU mismatch configurations between VPLS
nodes. The node ceases sending VPLS echo requests when the specified
VPLS ping is interrupted, or a VPLS echo response is not received after four successive retries.
The optional
the ip option is specified, the VPLS echo reply is routed back to the sender, specified in the L2 VPN
Prefix sub-TLV, via an IPv4 packet with the IP Router Alert option. If the
VPLS echo reply is routed back to the sender over an MPLS LSP. If no LSP is available, the VPLS echo
reply is not sent. When the
