Disables the Spanning Tree IGMP fast recovery.
vlan
VLAN-LIST
List of VLAN IDs, in the form {k|k1-k2} [, {l | l1-l2}[,{m|m1-m2}[,…
]]], where commas separate between terms and hyphens indicate
ranges.
The VLAN IDs are in the range <1-4094>.
For example: The expression 2,4,8-32,64-512 represents VLAN IDs 2,
4, the range from 8 to 32 and the range from 64 to 512.
ports
PORT-LIST
Port list, in the form
u[[/s[/p]]][-u[[/s[/p]]][,u[[/s[/p]]]]]...
Where
u
,
s
and
p
represent a 1- or 2-digit unit number, slot number
and port number respectively. The user can specify:
•
u
for all ports on unit number
u
;
•
u/s
for all ports on slot number
s
on unit
u
;
•
u/s/p
for port
p
on slot
s
on unit
u
;
•
a hyphenated range (blank spaces are not allowed);
•
a list, separated by commas (blank spaces are not allowed).
Example
The following example shows how to enable Spanning Tree IGMP fast recovery on VLANs and
ports:
device-name
(config)#
protocol
device-name
(cfg protocol)#
spanning-tree igmp-fast-recovery vlan 5-10,100
ports 1/1/1-1/1/8
Enabling/Disabling the Line Flapping Detection
The
spanning-tree line-flapping-detect
command, in Protocol Configuration mode, causes the
Root and Alternate ports to swap roles when the flapping (continued and uncontrolled link up and
down event ) appears on a physical interface.
Command Syntax
device-name
(cfg protocol)#
spanning-tree line-flapping-detect
{
enable
|
disable
}
Argument Description
enable
Enables the line flapping detection.
disable
Disables the line flapping detection.
