similar to: etherchannel/port group/bonding plus vlan works well

Andrew and Dennis are spot on. Their conclusions about your server being connected to an access port and not a trunk port would be my conclusion as well.

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can

Thank you everyone. OK, the mystery deepens, I guess. The machine does need to support several VLAN's, it is currently on a trunkport (8021q encapsulated), it made it into the ARP table - which I specifically tested for by physically unplugging the table, clearing the ARP table and plugging it back in. The ARP table currently looks like this: hq#show arp Protocol Address Age (min)

Hello all, I'm having unusual difficulty configuring teaming with Centos 4.2. The 2 NIC's are Broadcom. The HW is HP DL360 and there is no teaming driver for RHEL4 since it comes with package (says HP). Since there is no teaming driver from centos (as far as I know), I tried the Broadcom Driver, configured the team file, but the team just wont come up. A Virtual Interface should be up

Do you need the whole configuration? On the switch end, we have the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris. On Fri, Jan 23, 2015 at 8:54 PM, Dennis Jacobfeuerborn < dennisml at

I have recently upgraded my firmware from v6.3 to v7.4. Now when the phone is booted or rebooted, the initial screen "Initializing Vlan" takes forever to initialize before it initializes IP. Any ideas/Thoughts? (Trying not to Revert back to v6.3). -C -------------- next part -------------- An HTML attachment was scrubbed... URL:

OK, thanks again for all your help. I have resolved this, finally. The problem was that I configured VLAN 48 as the native VLAN on the trunk port.That was a mistake as apparently the native VLAN is the one where Cisco does not bother to tag packets. For now I set the native VLAN to VLAN 1 and that works. Cheers, Boris. On Sun, Jan 25, 2015 at 7:13 PM, Boris Epstein <borepstein at

This is mildly off topic since it has more to do with TCP/IP networking than with CentOS per se. However, at the risk of ruffling a few feathers I would like some advice on how to resolve the following routing problem: Given: dual homed host running CentOS-5.2 with eth0 = 2xx.yyy.zzz.23 eth1 = 192.168.219.1 and a Cisco gateway at 2xx.1xx.y7y.1 with the following networks: interface

Cisco phones act a as a switch. If you do not use the CDP protocol to "tell" the phone it needs to be in a special VLAN (802.1q) then it will just use the access port settings on the switch, and, also allow the PC connected to the 2nd Ethernet port to have access to the network. However, if you have an all cisco powered network, with all cisco phones, I could advise you to use the CDP

OK... but why does it need to be a trunk port? Boris.

Hi, I''m trying to increase the bandwidth between two hosts (backup). Both hosts are in the same /24 subnet and each of them is connected to a Cisco switch by 2 GbE interfaces (intel e1000).

A VLAN is basically a 4 byte "tag" that gets injected into the packet header when the packet enters the VLAN network. When we trunk a VLAN we say to the switch "pass packets on VLAN x but

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

Hi, I have the following Problem: My Rootserver stands at a hoster, I run a debian sarge and installed Xen 3 there latetly. I booted the xen Kernel - everything ok. However: when I started xend, the server instantly stopped responding. My Hosters Support said, that was due to a sort of mac spoofing protection in the switch, which disabled the Port, to which my server is connected, because there

This is almost certainly not an Asterisk-specific posting, but due to my inability to find a VoIP-focused Cisco list, I'll post here in the hopes of finding a more diverse user community. I am using a Cisco 7960 (version 6.0 SIP firmware) with Asterisk, and have been experiencing situations where the phone locks up. "Locks up" means that the bottom part of the screen

Hello, I've got an ISDN PRI circuit terminating in a Cisco AS5350, which in turn is talking to an Asterisk server via SIP for call origination and termination. Seems simple enough, and it works for the most part, but: 1) Caller ID name data comes in on the PRI, but doesn't appear to get handed off to the Asterisk server via SIP, at least not in any format that Asterisk
