Re: [swinog] EtherChannel - Long Time between LINK-3-UPDOWN and LINEPROTO-5-UPDOWN

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!

IPv6 Buddy Keypad

This special USB IPv6 number keypad doesn't seem to be a joke: http://www.ipv6buddy.com Even includes dedicated ":" and "::" buttons. Somebody should buy a 10-pack and sell them at next Swinog meeting. ;-) -- Andre

Astaro & PPPoE Einwahl Probleme
by Marcel Stutz 29 Mar '12

29 Mar '12

Hallo zusammen, Wir haben seit Montag morgen Probleme mit Kunden die ein Modem als Bridge (ADSL/VDSL) verwenden und dahinter eine Astaro Security Linux Firewall betreiben. Nach dem der Fall Eskaliert worden ist haben wir nun folgende Information bekommen. Zitat : Infinigate Swisscom DSL Update / 8.302 nach einem Update der Swisscom-DSL-Anbindungen bzw. deren Verhalten ist es vielen Kunden nicht mehr möglich, sich über das Astaro Security Gateway ins Internet einzuwählen. Der Grund hierfür liegt darin, dass Swisscom eine DSL-Einwahl nur noch alle fünf Minuten zulässt, was zur Folge hat, dass die Einwahl in vielen Fällen scheitert. Auch wenn das Problem in keinem direkten Zusammenhang mit der ASG steht, haben wir uns dazu entschlossen, ein offizielles "Update 8.302" zu veröffentlichen, welches die PPPOE-Einwahl dem neuen Verfahren der Swisscom anpasst. Dieses Update steht Ihnen im Laufe des Tages als Soft-Release auf unseren öffentlichen FTP-Servern zur Verfügung und kann über den WebAdmin manuell eingespielt werden. Mit freundlichen Grüßen Dominic Schmidl Director Support, Network Security Auch gibt es im Astaro Support Forum ein Hack/Workaround wer selber basteln will. http://www.astaro.org/astaro-gateway-products/network-security-firewall-nat… Hoffe dass hilft allen die seit Montag Klagende Benutzer/Firmen am Telefon hatten.
