To set the CIST Hello Time, enter the following command in root view:
root> ethernet mstp set cist-bridge-hello-time <cist-bridge-hello-time>
To set the CIST maximum number of hops, enter the following command in root view:
root> ethernet mstp set cist-bridge-max-hops <cist-bridge-max-hops>
Table 270 MSTP Bridge Level Spanning Tree CLI Parameters
Parameter Input Type Permitted Values Description
cist-bridge-
priority Number 0-61440, in steps of
4096. Enter a value as the writeable portion of the
Bridge ID. This value constitutes the first
two octets of the Bridge ID.
cist-bridge-
hold-time Number 10-100 Enter a value (in cs) as the interval length
during which no more than two
configuration bridge PDUs will be
transmitted by this node.
cist-bridge-
max-age Number 600-4000 Enter a value (in cs) that all bridges will use,
when this bridge is the root, as the
maximum age of MSTP information learned
from the network on any port before the
information is discarded.
cist-bridge-
forward-delay Number 400-3000 Enter a value (in cs) that all bridges will use,
when this bridge is the root, as the speed at
which ports change their spanning state
when moving towards the Forwarding state.
This value determines how long the port
stays in Listening state and Learning state.
This value is also used when a topology
change has been detected and is underway
for purposes of aging all dynamic entries in
the filtering database.
cist-bridge-
hello-time Number 100-1000 Enter the value (in cs) that all bridges will
use, when this bridge is the root, as the
Hello Time. The Hello Time determines how
often the switch broadcasts its hello
message to other switches, and is the same
for all MSTIs.
cist-bridge-
max-hops Number 6-40 Enter the value that all bridges will use,
when this bridge is the root, as the
maximum number of hops allowed for a
BPDU within a region before it is discarded.
