    Posted Aug 11, 2022 07:23 AM
    Hi,
    Is there any way to implement interface max auto-negotiate speed while maintaining auto-duplex on the AOS-CX range? (6100 specifically)
    Similar to "speed-duplex auto-10-100" on the Aruba/Procurve switches.
    Thanks

    Hello

    Please check in interface context the command speed auto . After auto you have the options to specify the max speed.
    Here an example, it is not exactly 6100 but a 6000, I think it should be similar.


    switch(config-if)# speed auto ?
    100g Allow interface to link at 100Gbps
    100m Allow interface to link at 100Mbps
    10g Allow interface to link at 10Gbps
    10m Allow interface to link at 10Mbps
    1g Allow interface to link at 1Gbps
    2.5g Allow interface to link at 2.5Gbps
    25g Allow interface to link at 25Gbps
    40g Allow interface to link at 40Gbps
    50g Allow interface to link at 50Gbps
    5g Allow interface to link at 5Gbps
    <cr>

    switch(config-if)# speed auto 100m
    switch(config-if)# show run current-context
    interface 1/1/1
    no shutdown
    speed auto 100m
    vlan access 1
    exit
    switch(config-if)# speed auto 100m ?
    100g Allow interface to link at 100Gbps
    10g Allow interface to link at 10Gbps
    10m Allow interface to link at 10Mbps
    1g Allow interface to link at 1Gbps
    2.5g Allow interface to link at 2.5Gbps
    25g Allow interface to link at 25Gbps
    40g Allow interface to link at 40Gbps
    50g Allow interface to link at 50Gbps
    5g Allow interface to link at 5Gbps
    <cr>
    switch(config-if)# speed auto 100m 10m
    switch(config-if)# show run current-context
    interface 1/1/1
    no shutdown
    speed auto 10m 100m
    vlan access 1
    exit

    Excellent! Thanks Emil.
    I was confused by the output from the speed command - didn't realise there were options after 'auto'.
    That's great though, just what I was looking for.

    Switch1(config-if)# speed
    10-full 10 Mbps, full duplex, no auto-negotiation
    10-half 10 Mbps, half duplex, no auto-negotiation
    100-full 100 Mbps, full duplex, no auto-negotiation
    100-half 100 Mbps, half duplex, no auto-negotiation
    auto Auto-negotiate speed and duplex
    Switch1(config-if)#
