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 12-2  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)

  • The blocked port in instance 0 of STP/RSTP/MSTP can block GVRP packets; the blocked ports of other MSTIs and other ring network protocols such as ERPS, SEP, RRPP, Smart Link, and VBST cannot block GVRP packets. To ensure that GVRP runs normally and prevent GVRP loops, do not enable GVRP on the blocked port of a ring network protocol.
  • The blocked ports of LDT and LBDT cannot block GVRP packets. To ensure that GVRP runs normally and prevent GVRP loops, do not enable GVRP on the blocked port of LDT and LBDT.
