 Globally configure the Virtual Port Channel settings.
1. In the VPC Mode field, select Enable or Disable to globally enable or disable the VPC
feature. By default, the VPC feature is Disabled.
The following table describes the non-configurable VPC Global Configuration fields.
Table 76. VPC Global Configuration
Field Description
Domain ID VPC Domain ID. Possible values are 1 to 1.
Device Role Device Role is either Primary, Secondary, or None,
based on an election between the two devices.
The
role is elected after a keepalive link is established.
The default is None.
System MAC The MAC address of the local system.
 Configure the Keepalive Parameters.
The VPC feature sends periodic keepalive messages over the peer link between the primary
and secondary devices in the VPC domain to determine the device roles (primary and
secondary) and to monitor the health of the link.
1. Enter the Keepalive Priority. Use this field to configure the priority value which is used
on a switch for primary and secondary role selection. The primary switch is responsible
for maintaining and propagating spanning-tree and link-aggregation state to the
secondary switch. The range is 1 to 255 seconds. The default is 100. The device with a
lower priority value becomes the Primary device in the VPC role election.
2. Enter the Keepalive
Timeout. Use this field to configure the number of seconds that must
pass without receiving a keepalive message before the peer device is considered to be
down. If an MLAG switch does not receive keepalive messages from the peer for this
timeout value, it then transitions its role (if required). The range is 2 to 15 seconds. The
default is 5 seconds.
3. Use the Keepalive
Admin Mode field to Enable or Disable the administrative mode of the
keepalive component on the device. If a VPC switch does not receive keepalive messages
from the peer within the timeout value, it begins the process of transitioning its role to
primary (if standby). By default, the Keepalive Admin Mode is Disabled.
