MSTP - Two new commands have been added to simplify MSTP management:
enable mstp port={port-list|all}
disable mstp port={port-list|all}
These commands enable or disable MSTP on the specified ports for the CIST and
all currently-configured MSTIs, in a single step.
Previously, this operation required two commands. For example, you can now use
enable mstp port={port-list|all} instead of the following commands:
enable mstp cist port={port-list|all}
enable mstp msti=instance port={port-list|all}

IP Gateway - When a router or switch receives a packet and does not have an ARP entry for
the destination address, it broadcasts an ARP Request message over the egress IP
interface. If it does not receive a reply within a short time, it notifies the sending
device that the destination was unknown.
This enhancement lets you configure how long the router or switch waits for a
response. Use the following new command to specify the timeout period in
seconds:
set ip arpwaittimeout=1..30
The default is 1 second. You may need to increase the timeout period if you are
communicating with devices that are slow to respond.
The easiest way to see the effect is to ping an unavailable device. The timeout
determines the delay between pinging an IP address and receiving the reply that
the device is unreachable.
