EtherChannel - Long Time between LINK-3-UPDOWN and LINEPROTO-5-UPDOWN
by Tobias Brunner 05 Apr '12

05 Apr '12

Hi there, Maybe there are some Cisco specialists reading this List =) On a WS-C3750X it tooks about 1 minute after connecting a port to change the status from LINK-3-UPDOWN "up" to LINEPROTO-5-UPDOWN "up" Mar 27 16:25:37 192.168.1.144 788: *Mar 8 00:30:48.032: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Mar 27 16:26:38 192.168.1.144 790: *Mar 8 00:31:49.227: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to up Mar 27 16:25:54 192.168.1.144 789: *Mar 8 00:31:05.086: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Mar 27 16:26:56 192.168.1.144 791: *Mar 8 00:32:06.583: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to up The ports are configured like that: interface GigabitEthernet1/0/1 switchport access vlan 27 switchport mode access spanning-tree portfast spanning-tree bpdufilter enable channel-group 1 mode active ! interface GigabitEthernet2/0/1 switchport access vlan 27 switchport mode access spanning-tree portfast spanning-tree bpdufilter enable channel-group 1 mode active ! interface Port-channel1 switchport access vlan 27 switchport mode access end The server which is connected has nothing special configured... It should boot via DHCP/PXE (of course without Bonding) and then the installed Linux with Bonding configured. Does anyone have an idea why this takes so long? Thanks!

Tobias: Now that you have shown this show interface command output and i see all the connections are flapping up and down for so long i am even more so convinced that this is a layer 1 problem and i am sure it has something to do with the cables. replace all the ethernet cables with NEW minmum CAT 6 cables and I would bet that the problem disappears straightaway. Let me know. Cheers!

I've merged all the input of you (and the trunk/vlan configuration I need to use) and this is how the configuration looks right now: interface GigabitEthernet1/0/1 switchport trunk encapsulation dot1q switchport trunk native vlan 27 switchport trunk allowed vlan 27,453 switchport mode trunk no cdp enable spanning-tree portfast trunk spanning-tree bpdufilter enable channel-group 1 mode active ! interface GigabitEthernet2/0/1 switchport trunk encapsulation dot1q switchport trunk native vlan 27 switchport trunk allowed vlan 27,453 switchport mode trunk no cdp enable spanning-tree portfast trunk spanning-tree bpdufilter enable channel-group 1 mode active ! interface Port-channel1 switchport trunk encapsulation dot1q switchport trunk native vlan 27 switchport trunk allowed vlan 27,453 switchport mode trunk spanning-tree portfast trunk spanning-tree bpdufilter enable end It's not possible to just configure the "channel-group" on the GiX interfaces and all the rest on Po1 (as suggested by Steven), I had to add at least the "switchport" settings (otherwise the switch complains about not compatible ports). The addition of the spanning-tree settings to Po1 did not change the behaviour either. Also the used cables should be OK. And now, when I power on the server, this is the output of the switch-log (The server boots from Network, then from local disk with Debian and bonding configured: Apr 4 09:00:06 192.168.1.144 152: *Mar 15 17:05:41.781: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:00:06 192.168.1.144 153: *Mar 15 17:05:41.781: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:00:15 192.168.1.144 154: *Mar 15 17:05:51.202: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:00:16 192.168.1.144 155: *Mar 15 17:05:52.250: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:00:17 192.168.1.144 156: *Mar 15 17:05:53.525: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:00:18 192.168.1.144 157: *Mar 15 17:05:54.607: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:00:30 192.168.1.144 158: *Mar 15 17:06:05.907: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:00:30 192.168.1.144 159: *Mar 15 17:06:05.924: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:00:32 192.168.1.144 160: *Mar 15 17:06:08.465: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:00:32 192.168.1.144 161: *Mar 15 17:06:08.482: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:00:47 192.168.1.144 162: *Mar 15 17:06:22.701: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:00:47 192.168.1.144 163: *Mar 15 17:06:22.718: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:00:49 192.168.1.144 164: *Mar 15 17:06:25.050: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:00:49 192.168.1.144 165: *Mar 15 17:06:25.285: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:00:54 192.168.1.144 166: *Mar 15 17:06:29.957: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:00:54 192.168.1.144 167: *Mar 15 17:06:30.116: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:00:56 192.168.1.144 168: *Mar 15 17:06:32.515: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:00:56 192.168.1.144 169: *Mar 15 17:06:32.641: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:01:35 192.168.1.144 170: *Mar 15 17:07:10.768: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:01:37 192.168.1.144 171: *Mar 15 17:07:13.125: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:01:59 192.168.1.144 172: *Mar 15 17:07:35.430: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:02:39 192.168.1.144 173: *Mar 15 17:08:15.142: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:02:56 192.168.1.144 174: *Mar 15 17:08:32.246: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:02:56 192.168.1.144 175: *Mar 15 17:08:33.253: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:03:00 192.168.1.144 176: *Mar 15 17:08:35.753: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:03:15 192.168.1.144 177: *Mar 15 17:08:51.649: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:03:16 192.168.1.144 178: *Mar 15 17:08:52.446: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down Apr 4 09:03:16 192.168.1.144 179: *Mar 15 17:08:52.672: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down Apr 4 09:03:19 192.168.1.144 180: *Mar 15 17:08:54.979: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:03:37 192.168.1.144 181: *Mar 15 17:09:13.308: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:04:22 192.168.1.144 182: *Mar 15 17:09:57.835: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to up Apr 4 09:04:23 192.168.1.144 183: *Mar 15 17:09:58.825: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up Apr 4 09:04:24 192.168.1.144 184: *Mar 15 17:09:59.722: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to up Apr 4 09:04:24 192.168.1.144 185: *Mar 15 17:09:59.832: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to up As you can see, the ports go up and down many times (very strange, but maybe this is "by-design"). And it takes always 1 minute between LINK-3-UPDOWN and LINEPROTO-5-UPDOWN. The thing that makes me thinking of that this should be explainable: Why does it take always 1 minute? Is there something that can be configured which causes this delay? What does the switch expect? What does it wait for? It's nice to get good input in this mailing list!
