Reference Guide

To stop sending keepalive packets, use the no keepalive command.
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.
Command Modes INTERFACE
Supported Modes Programmable-Mux (PMUX)
Command History
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 congure keepalive, the system sends a self-addressed packet out of the congured interface
to verify that the far end of a WAN link is up. When you congure 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 trac 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 Identier. The range is 1 to 4094.
Defaults Not congured.
Command Modes CONFIGURATION
Supported Modes Programmable-Mux (PMUX)

Version Description
9.4(0.0) Introduced on the FN I/O Aggregator.
9.3(0.0) Introduced on the M I/O Aggregator.
Usage Information
FCoE storage trac 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
specied fabric. You must congure a separate FCoE VLAN for each fabric to which FCoE trac is
forwarded. Any non-FCoE trac sent on a dedicated FCoE VLAN will be dropped.
You congure the association between a dedicated VLAN, which carries FCoE trac 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 congured as a
tagged member of the FCoE VLAN.
