DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
Enabling TC filtering on a port is useful for an ISP to prevent the external bridge to a core region of the
network, causing address flushing in that region, possibly because those bridges are not under the full
control of the administrator.
When a port is set to the TCN filter mode, the TC event received by the port will be ignored. This
configuration will take effect for all the spanning-tree modes.
Example
This example shows how to configure TCN filtering on port eth1/0/7.
Switch# configure terminal
Switch(config)# interface eth1/0/7
Switch(config-if)# spanning-tree tcnfilter
Switch(config-if)#
97-16 spanning-tree tx-hold-count
This command is used to limit the maximum number of BPDUs that can be sent before pausing for one
second. Use the no form of the command to restore the default setting.
spanning-tree tx-hold-count VALUE
no spanning-tree tx- hold-count
Parameters
VALUE
Default
By default, this value is 6.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command specifies the number of hold BPDUs to transmit. The transmission of BPDUs on a port is
controlled by a counter. The counter is incremented on every BPDU transmission and decremented once
a second. The transmissions are paused for one second if the counter reaches the transmit hold count.
Example
This example shows how to configure the transmit hold count value to 5.
Specifies the maximum number of BPDUs that can be sent before
pausing for one second. The range is from 1 to 10.
