metering on 40GE ports and higher

    Hi, all!

    Does anybody trying to configure meter higher then 10Gbps?
    Have information that there is no possibility to configure that.
    Where I can find this limitation?
    What reason for this limitation?

    Thank you!

    Hello Alexandr,

    I was able to configure 70 Gbps meter

    X870-96x-8c.8 # sh meter Name Committed Rate Peak Rate Burst Size ------------------------------------------------------------------------------- test 70000000 Kbps -- -- Total number of Meter(s) : 17 X870-96x-8c.9 # sh conf acl | i meter create meter test configure meter test committed-rate 70000000 Kbps out-actions drop
    [/code]

    Also a question.

    Could you, please, explain the general principle of which is limited max CIR value?

    Because on 10Gbps switches we have no possibility to configure meter more then 10G.
    But on 1Gbps switches we can configure meter more then 1G.

    For example X440
    # create meter Test

    # configure meter "Test" committed-rate 1 Gbps

    # configure meter "Test" committed-rate 5 Gbps

    # configure meter "Test" committed-rate 10 Gbps # configure meter "Test" committed-rate 11 Gbps

    Error: committed-rate cannot exceed 10 Gbps

    Thank you!

    That is depends of the higher supported speed per platform

    * X670-48x.3 # conf meter test1 committed-rate 5 Gbps * X670-48x.4 # conf meter test1 committed-rate 10 Gbps
    * X670-48x.5 # conf meter test1 committed-rate 20 Gbps
    Error: committed-rate cannot exceed 10 Gbps
    * X670-48x.6 # [/code]
    X670V-48t platfrom has 40GE uplink ports so:

    * X670V-48t.9 # conf test1 committed-rate 25 Gbps
    * X670V-48t.10 # conf test1 committed-rate 40 Gbps
    * X670V-48t.11 # conf test1 committed-rate 41 Gbps
    Error: committed-rate cannot exceed 40 Gbps
    * X670V-48t.12 #
    [/code]

    Hello, Nikolay!

    Thank you for clear answer!!!

    Am I understand right?

    As X440 has models with 10G uplinks, so all switches of X440 platform can configure up to 10G meter? (even X440-L2-24t)

    Thank you!

    Correct. X440 family could have uplinks/stack ports (both are 10GE) or be just "L2" model without front-end connected10GE interfaces and in all cases same chipsets with the same hardware limitations are used.
