M6100 Web Management User Guide 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 Device Role System MAC VPC Domain ID. Possible values are 1 to 1. 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. 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. Configuring Switching Information 201
