  • 1.  Juniper EX4400-48F 1/10g ports

    Hi,

    Just wondering do you have to do anything special to configure the 1/10g ports that the 4400 has 12 of? The only way i seem to get a 1g connection is by setting the speed and duplex manually at both ends. this Gives me connectivity but the link light is never solid and are constantly flashing? Is there something obvious I've missed?  Does it not support AutoNeg for 1g?

    10g works fine.

    THanks

    Hi Steven,

    If you want to configure them as 1gb configure the interface as ge-0/0/xx if you want to configure them as 10gb then you need to use xe-0/0/xx. 

    The link light is blinking because it is running at 1gb speeds and is only solid on sfp+ ports when running at 10gb. as described on table 5: https://www.juniper.net/documentation/us/en/hardware/ex4400/topics/topic-map/ex4400-chassis.html

    If you have configured the interface as ge- and using a 1gb optic you shouldn't have to manually set the speed and duplex it should just autoneg to 1gb.

    Many Thanks

    Harry

    Hi Harry,

    Thanks for the reply, i am indeed guilty of not reading the release notes and it was in fact indicating 1g speed. I feel a different colour LED would have been a better solution but thanks non the less!

    Kind Regards
