Configuring a VLAN MAC Address with Heartbeat
Interval
When installing HP routing switches in the place of existing routers in a
network configuration, you can achieve Layer 3 VLAN migration by using the
ip-recv-mac-address command at the VLAN configuration level to:
Configure the MAC address of the previously installed router on each
■
VLAN interface of a HP routing switch.
■ Optionally configure the time interval to use for sending heartbeat packets
with the configured MAC address.
Syntax: [no] ip-recv-mac-address <mac-address > [interval <seconds>]
ip-recv-mac-address <mac-address>
Configures a VLAN interface with the specified MAC
address. Enter the no version of the command to remove the
configured MAC address and return to the original MAC
address of the HP switch.
interval <seconds>
(Optional) Configures the time interval (in seconds) used
between transmissions of heartbeat packets to all network
devices configured on the VLAN. Valid values are from one
to 255 seconds. The default is 60 seconds.

Operating Notes

The ip-recv-mac-address command allows you to configure only one MAC
■
address for a specified VLAN. If you re-enter the command to configure
another MAC address, the previously configured MAC address is overwrit-
ten.
Enter the no form of the command to remove a configured MAC address
■
and restore the default MAC address of the HP switch.
■ When you configure a VLAN MAC address, you may also specify a heart-
beat interval. The interval <seconds> parameter is optional.
After you configure a VLAN MAC address:
■
• IP router and MAC ARP replies to other VLAN devices contain the
user-defined MAC address as the Ethernet sender hardware address.
• Outbound VLAN traffic contains the HP MAC address, not the config-
ured MAC address, as the source MAC address in packet headers.
