‐ If the trusted ports are off the CCEP, the arp inspection trust or dhcp snoop trust

command must be used on the CCEPs and ICL ports.

‐ DHCP and ARP entries are created on both MCT cluster devices if the flow traverses both

the CCEP and ICL.

• Hitless failover. If the failover operation is performed with a cluster configuration, the TCP session is

reestablished. The MAC addresses from the cluster peer devices are revalidated and programmed

accordingly.

• Hitless upgrade. If the upgrade operation is performed with a cluster configuration, the TCP session

is reestablished. The MAC addresses from the cluster peer devices are revalidated and

programmed accordingly.

The following FastIron features are not supported with MCT:

• LACP on ICL.

• MSTP, VSRP, RIP, OSPF, IS-IS, and BGP.

• Layer 3 multicast features. For example, PIM, MSDP, anycast RP, embedded RP etc.

• IPv6, VRRP-E (IPv6), and VRRPv3.

• GRE on the ICL VE interfaces.

• DAI on the CCEPs.

• Host security features (port MAC security, multi-port authentication, 802.1X, DAI, DHCP snooping)

on CCEPs.

• Multi-port ARP on ICL or CCEPs.

• Web authentication on MCT VLANs.

Basic MCT configuration

This section describes how to set up a basic MCT configuration. The following figure shows a basic

MCT topology, which applies to Layer 2 and Layer 3. MCT can also be supported with VRRP or

VRRP-E. See the section MCT for VRRP or VRRP-E on page 187.
