Active-Active MCT configuration considerations
•
On Customer Client Edge Ports (CCEP), MCT does not support the following features: 802.1ah,
802.1ad (listed in
“MCT feature interaction matrix”
as unsupported).
•
ICL ports should be not be an untagged member of any VLAN. An ICL is preferably a LAG that
provides port level redundancy and higher bandwidth for cluster communication.
•
On the Brocade MLX series and NetIron XMR, ICL ports can be part of MCT VLANs as well as
regular VLANs.
•
The Brocade MLX series, and NetIron XMR devices will disable MAC learning on ICL ports for
the VLANs configured in the cluster. However, MAC learning is enabled on ICL port for
non-cluster VLANs.
Flooding features (VLAN CPU protection, multicast
flooding etc.) on cluster VLANs.
802.1ah on CCEP or ICL ports.
Multi-VRF MSTP
UDLD as independent boxes.
VPLS on CCEP or ICL ports.
Link OAM as independent boxes.
VLL on CCEP or ICL ports.
802.1ag as independent boxes.
MPLS on CCE or ICL ports.
ARP as independent boxes.
Hitless Fail over is NOT supported on the Brocade MLX
series, and NetIron XMR, however it is compatible. If the
operation is performed with cluster configuration the TCP
session is reestablished. The MACs from the cluster peers
will be revalidated and programmed accordingly.
Brocade recommends shutting down all the CCEP ports on
the cluster node so that there is graceful failover and then
hitless operation can be performed.
STP and RSTP
Port MAC Security on the node where it is
programmed.
Hitless Upgrade is NOT supported, on the Brocade MLX
series, and NetIron XMR, however it is compatible. If the
operation is performed with cluster configuration the TCP
session is reestablished. The MACs from the cluster peers
will be revalidated and programmed accordingly.
Brocade recommends shutting down all the CCEP ports on
the cluster node so that there is graceful failover and then
hitless operation can be performed.
802.1x on the node where it is programmed.
Multi-port MAC are not supported on ICL or CCEP ports.
Configuration will be rejected when trying to configure
multi-port MAC addresses with a port mask which
contains either a CCEP port or ICL port and vice-versa on
the Brocade MLXe, NetIron MLX and NetIron XMR.
Static MAC configuration - Static MACs are
programmed on both local and remote peers as
static entries.
Multi-port ARP will not be allowed on ICL or CCEP ports on
the Brocade MLX series and NetIron XMR.
