Re: [swinog] cisco switches: new config with vlan defintion is not applied to startup-config for some reason
Hi Erich Thank you for your answer. I also saw this in the documentation. But the switch behaves differently. If I have a switch with already configured vlans with vtp mode transparent (with the same infos in vlan.dat ) then only the higher numbered vlans are going to be applied from the startup config. The lower numbered vlans are copied from vlan.dat to the configuration.

[swinog] cisco switches: new config with vlan defintion is not applied to startup-config for some reason
Hi list During a future migration I will migrate the configuration of around onehundert already existing switches. Because I am lazy as many it guys I prepared the configs which I want to apply to the switches in order to safe time. Many things change from the previous config to the future one: lacp uplinks, vlan defintions, management vlan and so on. So during the miration I want to do something like this: copy tftp://10.6.100.3/config.txt startup-config and do a reload or configure replace tftp://10.6.100.3/config.txt I tested my miration path in the lab and I figured out that low numbering vlans in the range of 2-1001 are for some strange reason not applied to the config. I tried also deleting vlan.dat and change to vtp of or transparent/server/client and diffrent vtp versions before applying the config without success. Does somebody have a clou about the strange behaviour? I use iso version 15.0(2)SE on a 2960S Cheers Luke ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

[swinog] Private VLAN with none-private-vlan speaking switch in between
Hi Does somebody know if its possible to connect two private-vlan speaking switches (Cisco 3560/3750) with a none-private-vlan speaking switch in between? Does that work so that I can still use the community/isolated vlans on both private-vlan speaking switches?

Re: [swinog] EtherChannel - Long Time between LINK-3-UPDOWN and LINEPROTO-5-UPDOWN
Hi Tobias Here are perhaps some hints... -channel-group NUMBER mode on: Is a static channel with NO channel protocol on it. If you speak LACP on the other side the channel won't come up because the neighbors don't agree to a channel. You need a "channel-group NUMBER mode active" on the switch side so it speaks LACP. Set it to this mode and run a debug on the switch so you can see more: debug lacp ? See: (http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/15.0_1_se/command/reference/cli1.html#wp11890010) You can also fix the channel only to speak LACP with "channel-protocol lacp" in combination with "channel-group NUMBER active". See: (http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/15.0_1_se/command/reference/cli1.html#wp11890203) -switchport nonegotiate: disables DTP (dynamic trunking protocol) which is used to negotiate a trunk between to dtp speaking switches. If you set the port to "switchport mode trunk" on the switch side then you make a trunk on this port. See: (http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/15.0_1_se/command/reference/cli3.html#wp1948171) . So in my point of view you don't need the "switchport nonegotiate" command. -speed 1000: if you fix the speed to 1Gbit then its always full duplex. There is no 1Gbit with halfduplex as far as I know. So the duplex full is also useless on this port. Generally speaking: If you fix the duplex mode and speed one side please watch out that you also fix it on the other side. So I would frist watch out that the channel comes up. For trunking and vlans on the trunks you can troubleshoot later. Cheers Luki Am 05.04.2012 16:21, schrieb Tobias Brunner: Hi everyone, I've "compiled" all your input, here is the output: The cables are all cat5e, which should be OK. But to be sure I've managed to find a cat6 cable, but as expected, it did not change anything. So the cables are not the problem. Then I added "speed 1000" and "duplex full" to the two port configuration, but: no change. Next step: Try "mode on" -> Does not work because "on" is PAGP which is not compatible with LACP. Go on: Try "switchport nonegotiate" -> No change in behaviour. When the servers are booting (BIOS, not yet OS) then there is no bonding/etherchannel available. Both ports are independent. That should be no problem for the "mode active/passive" and it works as expected, the server can do DHCP/PXE during boot. But it takes a long time until the server gets an IP from DHCP because it takes so long to get the protocol up. Is your server supporting LACP? During BIOS boot: no While running OS: yes How are is the bonding configured on the interfaces? During BIOS boot: not configured While running OS: configured with linux bonding (that works fine) Maybe this will stay a mysterium =) I wish everyone good luck in finding the easter-eggs. (Maybe this behavior is a cisco-easter-egg and solved after easter, who knows =) Cheers, Tobias ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
