catalyst 4500-X SFP issues

[Sivan]

Hello guys,

I have a Catalyst 4500-X switch which is having all TenGigabyteEthernet ports. I am using a mix of 10Gbe SFP fibre modules and 1 Gbe SFP Ethernet modules. My issue is some of the ports doesn't comes up if i remove and reconnect the cables (or restart the device which is connected on the port). I may need to remove the SFP module in that port multiple times and reconnect again, then only it comes. Once its up its working fine. Even if i connect my laptop to any of these ports, it doesn't show any connection. Please help. Is that something to configure on that ports or switch... All the ports are in Static access administrative mode and part of a VLAN. If i change the port speed to 1Gbe or 10Gbe according to devices attached will it help ?.. please advice.

Can we have more information about the modules, and SFP information.

show version

show modules

show interface information (where you have issue)

Dear Balaji,

Attached the response. The interface status by using "show interfaces" command. Attached them. My issue is main on port 1/1 and port 1/2. Both are in a single VLAN 31. The sttus on these ports shows not connected Line protocol is down. If i remove the SFP and reconnect it , then it starts working.

Hi Sivan

have you tried hard coding the port as its copper  GLC-T SFP, that will remove negotiation ?

speed 1000, duplex full

see if that makes a difference

Are these ports directly connected or is there a patch panel in between?

[Sivan]

Dear Mr.Mark,

These ports are directly connected. 

[Sivan]

Dear Mr.Balaji & Mark,

I have tried to change the port speed, but that doesn't allow me to change the port speed. i am getting error as below

Harmonic_Switch_A#config t
Enter configuration commands, one per line. End with CNTL/Z.
Harmonic_Switch_A(config)#interface ten
Harmonic_Switch_A(config)#interface tenGigabitEthernet 1/10
Harmonic_Switch_A(config-if)#speed 1000, duplex full
^
% Invalid input detected at '^' marker.

Harmonic_Switch_A(config-if)#speed 1000
^
% Invalid input detected at '^' marker.

Harmonic_Switch_A(config-if)#

I have tried with CNA, but still its the same returns me an error.

kindly suggest. 

[Mark Malone]

1 command at a time as below
There is a copper SFP in that port yes ?

Harmonic_Switch_A(config)#interface tenGigabitEthernet 1/10
Harmonic_Switch_A(config-if)#speed 1000
Harmonic_Switch_A(config-if)#duplex full

[Sivan]

Dear Mr.Mark,

Yes those are copper SFPs except the ones connected in ports 11-16 (using 10G fiber)

The commands returns as below

i just tested this on a 4500x
duplex command not available and with GLC-T in place you can only do speed 100, try that below

xxxxxx(config)#int t1/1/15
xxxxxx(config-if)#spe
xxxxxx(config-if)#speed ?
10 Force 10 Mbps operation
100 Force 100 Mbps operation


xxxxxxxxxx#sh int t1/1/15 | i Base
Full-duplex, 100Mb/s, link type is auto, media type is 1000BaseT

Hi Mr.Mark,

I really need these ports to be working in 1Gbe... So changing to 100 mbps wont work for me. But i will try this to make sure, my issues are because of that. I am not even able to connect my laptop to these ports. Don't know what i will do. A low priced HP Procurve switch works better than this without any of these mess ups.  :(

[Mark Malone]

Hi
Could you not use a glc-sx-mmd fibre 1gb connection then instead, the 4500x is a fibre switch really a distribution switch 10gb , you could check what options your has by using the tab question mark ? too when your glc-t is connected to see if you have a 1gb copper option , mine does not as i posted but qe use ut as a 10gb distribution switch

[balaji.bandi]

Full-duplex, Auto-speed, link type is auto, media type is 1000BaseT

This could be the reason, as suggest other post, set the speed 1G, connect the Laptop and test before actually connecting real port.So this confirm port working as expected.

[Sivan]

Dear Mr.Balaji,

Currently if i am connecting my laptop it doesn't work on these ports. So let me try this to force for 1G then will let you know. Thank you for your efforts and i will update you soon

[Mark Malone]

Hi
Looking at the supported guide you should be able to do 1000mb with a GLCT , it gives 3 different versions of software as minimum though , what version are you on ? ia m on 3.8.7 maybe try the later 3.10

Hi Mark,

I am on Version 03.06.03.E. I tried to update the software via CNA GUI, but it returns me a message saying File size is bigger than allowed in TFTP server. So i scared to do as i dont know the right procedure to do. Also its a bit expensive switch. I have the latest ROM bin file, but let me know how to update this.
