‐
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
