Chapter 16 ERRP COMMAND CONFIGURATION

16.1 Brief introduction of ERRP

ERRP (Ethernet Redundant Ring Protocol) is the private Ethernet ring protocol of QTECH

which is used to protect real-time service (vedio/voice delay sessitive service). The basic

working theory is many switches serial connect to be ring to provide link redundancy, and a

master device detects/maintains the ring. The master device provides redundant port which

can release redundant port when the ring break down to guarantee the service smooth. The

calculation is less, so the convergency is faster than STP.

16.2 ERRP Configuration

16.2.1 ERRP Configuration list

Only when ERRP and ring enable, the configuration can be effective.theconfiguration will be

reserved when ERRP and ring disable and it will be effective when ERRP and ring enable next

time.

 ERRP configuration

 Configure ERRP timer

 Enter ERRP configuration mode

 Configure control-vlan in ERRP domain

 Create ERRP ring

 Enable/disable ERRP ring

 Show ERRP domain and ring

16.2.2 ERRP configuration

Configure it in global configuration mode:

ERRP

no ERRP

It is defaulted to disable ERRP.

For example:

! Enable ERRP

QTECH(config)#ERRP

16.2.3 Configure ERRP timer

Configure it in global configuration mode:

 Configure packet overtime

ERRP fail-timer timer-value

Parameter:

timer-value: integrity in the range of 1-10

 Configure packet sending interval

ERRP hello-timer timer-value

Parameter:

timer-value: integrity in the range of 1-10

For example:
