Description
Extreme Networks EAS 100-24t Switch CLI Manual
maxage <value 6-40> - This value may be set to ensure that old information
does not endlessly circulate through redundant paths in the network,
preventing the effective propagation of the new information. Set by the Root
Bridge, this value will aid in determining that the switch has spanning tree
configuration values consistent with other devices on the bridged LAN. If the
value ages out and a BPDU has still not been received from the Root Bridge,
the switch will start sending its own BPDU to all other switches for permission
to become the Root Bridge. If it turns out that your switch has the lowest
Bridge Identifier, it will become the Root Bridge. The user may choose a time
between 6 and 40 seconds. The default value is 20.
maxhops <value 6-40> - The number of hops between devices in a spanning
tree region before the BPDU (bridge protocol data unit) packet sent by the
switch will be discarded. Each switch on the hop count will reduce the hop
count by one until the value reaches zero. The switch will then discard the
BDPU packet and the information held for the port will age out. The user may
set a hop count from 6 to 40. The default is 20.
hellotime <value 1-2> - The user may set the time interval between
transmission of configuration messages by the root device, thus stating that
the switch is still functioning. A time between 1 and 2 seconds may be
chosen, with a default setting of 2 seconds.
NOTE: In MSTP, the spanning tree is configured by port and therefore, the
hellotime must be set using the configure stp ports command for switches
utilizing the Multiple Spanning Tree Protocol.
forwarddelay <value 4-30> - The maximum amount of time (in seconds) that
the root device will wait before changing states. The user may choose a time
between 4 and 30 seconds. The default is 15 seconds.
txholdcount <value 1-10> - The maximum number of BPDU Hello packets
transmitted per interval. The default value is 6.
fbpdu [enable | disable] - Allows the forwarding of STP BPDU packets from
other network devices when STP is disabled on the switch. The default is
enable.
Only Administrator-level users can issue this command.
Used to set up STP on the port level.
config stp ports <portlist> {externalCost [auto | <value 1-200000000>] |
hellotime <value 1-2> | migrate [yes | no] | edge [true | false | auto] |
restricted_role [true | false] | restricted_tcn [true | false] | p2p [true | false
| auto] | state [enable | disable] | fbpdu [enable | disable]}
This command is used to create and configure STP for a group of ports.
