Mda Warm Swap - Avaya Virtual Services Platform 7000 Series Installation Manual

New in this release
FI port
DOWN 2 (bottom left) SPB (Fabric-mode
On the rear of each VSP 7000 chassis is a pair of FI-up and FI-down ports. In each FI port pair
there is a top and bottom connector. In rear port mode, each top connector can provide up to
three 40 Gbps ports, and each bottom connector can provide one 40 Gbps port.
You can use a rear port mode and connect the FI ports between multiple stand-alone VSP
7000 units to deploy a Fabric-mode DToR or Raw-mode configuration. Fabric-mode DToR
leverages the Shortest Path Bridging (SPB) protocol. Standard is a Raw-mode, that can
support various port configurations and protocols, such as Inter-Switch Trunking (IST) for
Switch Clustering.
Note:
Due to the different bandwidth of the FI port top and bottom connectors, you must connect the
top connector to the top connector of another unit, and connect the bottom connector to the
bottom connector of another unit.
Important:
Do not interconnect the FI ports of a VSP 7000 unit operating in Fabric-mode DToR or Raw-
mode with a VSP 7000 unit operating in Stack-mode DToR. This is an invalid configuration
that causes the rear port mode enabled switch to show ports 33–40 as enabled and up,
while the stack unit ports 33–40 are not visible and not available.

MDA warm swap

Media Dependent Adapter (MDA) warm swap is supported. You can warm insert, warm
remove, or hot remove an MDA.
You can perform a warm insert by enabling the MDA once it is inserted in a unit. You must
enable an MDA for the MDA ports to function. An MDA insertion event does not interrupt traffic
within the switch or stack.
You can perform a warm removal by disabling the MDA before removal. A warm removal
ensures MDA egress traffic routes to an operating switch port. Hot removal is also supported,
however a hot removal can cause packet loss. Once an MDA is hot removed, packets
scheduled to egress the MDA ports are discarded, and an unsafe MDA removal log message
is generated.
When the MDA is disabled, you no longer can modify the MDA port settings. The MDA settings
for auto-negotiation, auto-negotiation advertisements, speed, duplex, flow control, rate-
limiting, and admin status revert to their defaults when the MDA becomes active. All other
