configuration assistence - configure port for link to external access port

[julxu]

HI

I think it is easy for configuration a port, but I can not make it work:

I need configure an external 1G cat6 cable link to my cat6500, and I have been told this is on access port with BPDU disabled.  an ip should be assigned to it, ip address assume is 10.1.1.1/30

interface GigabitEthernet2/4/47
 description external 2
 switchport
 switchport access vlan 1496
 switchport mode access
 spanning-tree portfast disable
 spanning-tree bpduguard disable
 spanning-tree link-type point-to-point
end

I see the log:

Feb 10 17:07:36 AEDT: %LINK-SW1_SP-3-UPDOWN: Interface GigabitEthernet2/4/47, changed state to down
Feb 10 17:07:43 AEDT: %LINK-3-UPDOWN: Interface GigabitEthernet2/4/47, changed state to up

Feb 10 17:07:47 AEDT: %LINEPROTO-SW1_SP-5-UPDOWN: Line protocol on Interface GigabitEthernet2/4/47, changed state to down

I have also tried to put ip address direct on port. (no switchport; ip address 10.1.1.1 255.255.255.252) not work also.

Could I get some advice, what problem can be? how do I trouble shooting this issue.

Any comments will be appreciated

Thanks in advance

Is the configuration above from your 6500 ?

If so you should be able to do a "no switchport" and then assign an IP.

When you say it didn't work what exactly do you mean ?

it disn't work - means the when you show interface status, it is notconnect. it also means can not ping another end.

If it is showing as notconnect then it is nothing to do with the configuration in terms of L2 switchport or L3 routed port.

You have a link level problem.

What are you connecting to the 6500 ?

Jon

[julxu]

cat 6 cable.

[Jon Marshall]

What device is on the other end ?

Jon

[julxu]

no at this stage, will ask them tomorrow.

[julxu]

Finally, it works now, the reason is one site has spanning tree enabled, anotehr one is not. it automatically disabled the link.

now I have new problem. after it is online, the 1G port only become 100mb now.

replace my site cable do not fix the problem.

Gi1/4/47    xxxxxx   connected    46         a-full  a-100 10/100/1000BaseT

another end is a cat3650.

Any advice, please.

[julxu]

is anyway I can confirm it is link level issue?

external put link in, and at my site, only patch a cat 6 cable. no capability to say it is a link issue. do I?

[Jon Marshall]

What is connected to the other end of the cable ?
