In a VSX cluster, certain configurations such as DHCP relay need to be synchronized between both nodes. To sync DHCP relay configuration from the primary to the secondary, the command:

vsx-sync dhcp-relay

must be added under the VSX configuration on the primary switch. This ensures that DHCP relay settings are pushed to the secondary member automatically.

Adding vsx-sync ip-helper relates to IP helper addresses, not DHCP relay specifically.

Adding the sync command on the secondary has no effect as synchronization originates from primary.

This question involves OSPF peering configured between CX 6300 switches using BFD (Bidirectional Forwarding Detection). BFD parameters include transmit (Tx) and receive (Rx) intervals.

Switch B has custom BFD interval values configured, but switch A is at default configuration.

According to Aruba CX default BFD parameters, the Tx and Rx intervals default to 2000ms (2 seconds). This is why switch A’s show BFD session displays intervals of 2000ms even if switch B uses different values.

BFD interval negotiation results in the highest Tx/Rx interval being used, or default in case one side is unconfigured.

The Local Priority (LP) applied to an incoming packet marked with DSCP 46 and CoS 7 depends on the configured QoS mapping.

DSCP 46 corresponds to Expedited Forwarding (EF), which is typically mapped to the highest priority.

CoS 7 also indicates high priority.

According to the QoS policy shown, the LP assigned is 1, indicating the highest priority level.
