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.
