Set RSTP Bridge Hello Time
Command Name
rstp set bridgehellotime
Description
To set the HelloTime for a given Vlan-Id.
With STP, Hello Time is the time intervals that the root bridge sends out
new BPDUs to the rest of the network. Other STP capable switches will
forward these BPDUs along. With RSTP every RSTP capable switch will
generate new BPDUs and send them out on every Hello Time Interval.
Syntax
rstp set bridgehellotime <vlan-id> <hellotime>
Parameters
vlan-id
Vlan Id for which the priority is to be set.
hellotime
Hello Time to be set.
The valid range of the Hello Time is (1.0-10.0)secs.
Examples
N-TRON/Admin#[1]> rstp set bridgehellotime 1 2
N-TRON/Admin#[2]> rstp set bridgehellotime 2 5
NOTES
Please ensure that the hellotime and vlan id values are valid
Get RSTP Bridge Hello Time
Command Name
rstp get bridgehellotime
Description
To get the Hello Time of a given Vlan Id.
Syntax
rstp get bridgehellotime<vlan-id>
Parameters
vlan-id
Vlan Id for which the hellotime is to be viewed.
Examples
N-TRON/Admin#[1]> rstp get bridge hellotime 1
N-TRON/Admin#[2]> rstp get bridge hellotime 2
NOTES
Please supply valid Vlan Index ( being greater than zero)
Set RSTP Bridge Max Age
Command Name
rstp set bridgemaxage
Description
To set the Max Age for a given Vlan-Id. RSTP Max Age is the time the
switch waits after receiving a BPDU from the root bridge before declaring
that there is no longer a valid path to the root bridge (therefore he attempts
to become the new root bridge on the network). RSTP will only use this as
a backup feature, and to allow compatibility with older STP devices.
Syntax
rstp set bridgemaxage <vlan-id> <maxage>
Parameters
vlan-id
Vlan Id for which the priority is to be set.
maxage
The Max Age to be set.
The valid range for maxage is 6.0-40.0 secs. (IEEE 802.1D)
Examples
N-TRON/Admin#[1]> rstp set bridgemaxage 1 7
N-TRON/Admin#[2]> rstp set bridgemaxage 2 40
NOTES
Please ensure that the max age and vlan-id are valid.
Get RSTP Bridge Max Age
Command Name
rstp get bridgemaxage
Description
Gets the Bridge max age of the given Vlan-Id.
Syntax
rstp get bridgemaxage <vlan-id >
Parameters
vlan-id
Vlan ID for which the maxage is to be viewed.
Examples
N-TRON/Admin#[1]> rstp get bridgemaxage 1
N-TRON/Admin#[2]> rstp get bridgemaxage 2
NOTES
Please supply valid vlan Index ( being greater than zero)
