Displaying Flexlink Information
Use the show flexlink all
command to display brief information about all Flexlink instances configured on
the
device.
device(config)# show flexlink all Active Interface Backup Interface State --------------------------------------------------------- ethernet 1/1/9 ethernet 1/1/10 Active Up/Backup FL-Backup lag 10 lag 11 Active Up/Backup FL-Backup
Use the show flexlink all
detail command to display detailed information about all Flexlink
instances configured on the device.
device(config)# show flexlink all detail Active Interface Backup Interface State --------------------------------------------------------- ethernet 1/1/9 ethernet 1/1/10 Active Up/Backup FL-Backup Preemption Mode: forced Preemption delay: 100 Bandwidth : 1/1/9 (1Gbit), 1/1/10 (1Gbit) lag 10 lag 11 Active Up/Backup FL-Backup Preemption Mode: Bandwidth Preemption delay: 100 Bandwidth : lg10 (20G), lg11 (10G)
Use the show flexlink
interface command to display brief information about a specific Flexlink
interface (physical interface).
device(config)# show flexlink interface ethernet 1/1/9 Active Interface Backup Interface State --------------------------------------------------------- ethernet 1/1/9 ethernet 1/1/10 Active Up/Backup FL-Backup
Use the show flexlink
interface command with the detail keyword to display
detailed information about a specific Flexlink interface (physical interface).
device(config)# show flexlink interface ethernet 1/1/9 detail Active Interface Backup Interface State --------------------------------------------------------- ethernet 1/1/9 ethernet 1/1/10 Active Up/Backup FL-Backup Preemption Mode: forced Preemption delay: 100 Bandwidth : 1/1/9 (1Gbit), 1/1/10 (1Gbit)
Use the show flexlink
interface command to display brief information about a specific Flexlink
interface (LAG interface).
device(config)# show flexlink interface lag 10 Active Interface Backup Interface State --------------------------------------------------------- lag 10 lag 11 Active Up/Backup FL-Backup
Use the show flexlink
interface command with the detail keyword to display
detailed information about a specific Flexlink interface (LAG interface).
device(config)# show flexlink interface lag 10 detail Active Interface Backup Interface State --------------------------------------------------------- lag 10 lag 11 Active Up/Backup FL-Backup Preemption Mode: bandwidth Preemption delay: 100 Bandwidth : lg10 (20G), lg11 (10G)
The following example displays the Flexlink running configuration under the active link interface. The backup link does not generate any configuration.
device(config)# show running-config interface ethernet 1/1/9 ethernet 1/1/10
interface ethernet 1/1/9
no spanning-tree
flexlink backup interface ethernet 1/1/10
flexlink preemption mode forced
flexlink preemption delay 100
interface ethernet 1/1/10
