[j-nsp] J6350's interface down/up

[EVAN WILLIAMS]

check out clause 37 in auto-negotiation IEEE802 standard, you will need to explicitly set the speed and duplex settings. Auto-negotiation works for cisco to cisco and on occasions to HP procufve, far too often the auto-negotiation fails with other vendors.
Clause 37 says vendors develop their own auto-negotiation , a cop out I know.

Go for lowest denominator and configure up until you achieve the speed duplex you require

Some devices implicitly disable auto-negotiation when you explicitly
configure speed and duplex settings. For J-series interfaces, the Fast
Ethernet PIMs automatically disable auto-negotiation if you configure
both speed and duplex settings. The Gigabit Ethernet PIMs do not, if you
want to disable auto-negotiation on GE you will have to do so under
gigether-options.

If you have a link where one end is doing auto-negotiation and the other
is not, you will end up with the first end (the one doing auto-neg) in
half-duplex. This is the specified default according to 802.3u.

Thanks,
