Configuring distributed trunking

The following parameters must be configured identically on the peer devices or undesirable behavior in traffic flow may occur:

  • The ISC link must have a VLAN interface configured for the same VLAN on both DT switches.

  • VLAN membership for all DT trunk ports should be the same on both DT switches in a DT pair.

  • IGMP-snooping or DHCP-snooping configuration on a DT VLAN should be the same on both DT switches. For example, for a DT, if IGMP-snooping or DHCP-snooping is enabled on a VLAN that has a DT port as a member port of the VLAN, the same must be configured on the peer DT on the same VLAN.

  • Loop-protection configuration on a DT VLAN should be the same for both DT switches.
