Chapter 19 FLEX LINKS CONFIGURATION
19.1 Brief introduction of Flex links
Flex links is layer 2 links backup protocol which provides for STP option scheme. Choose Flex
links to realize link backup when the STP is not wanted in customer network. If STP enables,
flex links is disabled. Flex links consists of a pair of interfaces (can be ports or convergent
interface) . One interface is transmitting data, the other is standby. The backup interface starts
transmitting data when there is default in master link. The failure interface willl be standby
when it turns well and it will be transmitting data in 60 seconds when preempt mechanism is
set. Flex links interface should disable STP and Flex links interface can configure bandwidth
and delay being preempt mechanism and the superior one will be the master interface. There
must be trap alarm when master or backup link default.
19.2 Flex links Configuration
19.2.1 Flex links Configuration list
Enable or disable Flex links of interface(or convergent interface)
Configure Flex links preemption mode
Configure Flex links preemption mode delay
Disaply Flex links information
19.2.2 Enable or disable Flex links of interface(or convergent
interface)
Configure interface Flex links in interface configuration mode
switchport backup { interface interface-num | channel-group channel-group-number}
Configure channel-group Flex links in global configuration mode:
channel-group channel-group-number backup { interface interface-num | channel-group
channel-group-number}
For example:
! Configure flex links backup interface of e0/0/1 to be e0/0/2
QTECH(config-if-ethernet-0/0/1)#switchport backup interface Ethernet 0/0/2
! Configure flex links backup interface of channel-group 1 to be e0/0/2
QTECH(config)#channel group 1 backup interface Ethernet 0/0/2
19.2.3 Configure Flex links preemption mode
Configure interface Flex links in interface configuration mode
switchport backup { interface interface-num | channel-group channel-group-number}
preemption mode {Forced|Bandwidth|Off}
Configure channel-group Flex links in global configuration mode:
channel-group channel-group-number backup { interface interface-num | channel-group
channel-group-number} preemption mode {Forced|Bandwidth|Off}
For example:
! Configure flex links preemption mode of e0/0/1 to be Forced
QTECH(config-if-ethernet-0/0/1)#switchport backup interface Ethernet 0/0/2 preemption mode
Forced
