Feature Limitations

When many dynamic VLANs need to be registered or the network radius is large, using default values of timers may cause VLAN flapping and high CPU usage. In this case, increase values of the timers. The following values are recommended depending on the number of VLANs.

Table 8-5 Relationship between GARP timer values and number of dynamic VLANs that need to be registered

Timer

Number of Dynamic VLANs to Be Registered (N)

N <= 500

500 < N <= 1000

1000 < N <= 1500

N > 1500

GARP Hold timer

100 centiseconds (1 second)

200 centiseconds (2 seconds)

800 centiseconds (8 seconds)

1000 centiseconds (10 seconds)

GARP Join timer

600 centiseconds (6 seconds)

1200 centiseconds (12 seconds)

4000 centiseconds (40 seconds)

6000 centiseconds (1 minute)

GARP Leave timer

3000 centiseconds (30 seconds)

6000 centiseconds (1 minute)

20000 centiseconds (3 minutes and 20 seconds)

30000 centiseconds (5 minutes)

GARP LeaveAll timer

12000 centiseconds (2 minutes)

24000 centiseconds (4 minutes)

30000 centiseconds (5 minutes)

32765 centiseconds (5 minutes and 27.65 seconds)

Configuration Notes
  • GVRP can be configured on the trunk interface only.

  • Switches on a network need to use the same settings of GVRP timers; otherwise, flapping may occur in the dynamic VLAN.

  • Global GVRP and VLAN-based Spanning Tree (VBST) cannot be configured simultaneously, and GVRP and Multichassis Link Aggregation Group (M-LAG) cannot be configured on an Eth-Trunk simultaneously.

  • The blocked port of STP, RSTP, MSTI 0, ERPS, or Smart Link can block GVRP messages.

  • The dynamic VLAN that is registered through GVRP cannot be configured as a reserved VLAN or the default VLAN configured by the port default vlan command. Information about a reserved VLAN cannot be transmitted to other devices through GVRP.
