Parameters
seconds (OPTIONAL) For interfaces with PPP encapsulation enabled, enter the number of
seconds between keepalive packets. The range is from 0 to 23767. The default is
10 seconds.
Defaults Enabled.

Version Description
9.4(0.0) Supported on the FN I/O Aggregator.
8.3.17.0 Introduced on the M I/O Aggregator.
Usage
Information
When you configure keepalive, the system sends a self-addressed packet out of the configured
interface to verify that the far end of a WAN link is up. When you configure no keepalive, the system
does not send keepalive packets and so the local end of a WAN link remains up even if the remote end is
down.
interface vlan (NPIV proxy gateway)
Create a dedicated VLAN to be used to send and receive Fibre Channel traffic over FCoE links between servers and a fabric
over an Aggregator with the PMUX module of NPIV proxy gateway.
Syntax
interface vlan vlan-id
Parameters
vlan-id Enter a number as the VLAN Identifier. The range is 1 to 4094.
Defaults Not configured.

9.3(0.0) Introduced on the M I/O Aggregator.
Usage
Information
FCoE storage traffic received from servers on an M I/O Aggregator with the PMUX module NPIV proxy
gateway is de-capsulated into Fibre Channel packets and forwarded over FC links to SAN switches in a
specified fabric. You must configure a separate FCoE VLAN for each fabric to which FCoE traffic is
forwarded. Any non-FCoE traffic sent on a dedicated FCoE VLAN will be dropped.
You configure the association between a dedicated VLAN, which carries FCoE traffic from server CNAs
over the NPIV proxy gateway to a SAN fabric in which destination storage arrays are installed, in an FCoE
map by using the fabric id vlan command.
When you apply an FCoE map to a server-facing Ethernet port, the port is automatically configured as a
tagged member of the FCoE VLAN.
For more information about VLANs and the commands to configure them, refer to the Virtual LAN
(VLAN) Commands section.
