Trunking problem
I have a 5500 that one SUP w/ uplink will not go into trunk mode for anything. Currently it looks like this:
Port Name Status Vlan Level DuplexSpeed Type
1/1 Trunk to SW01 5/5 connected trunk high full 100 100BaseFX MM
1/2 Trunk to SW02 5/5 connected trunk high full 100 100BaseFX MM
2/1 standby 1 high full 100 100BaseFX MM
2/2 standby 1 high full 100 100BaseFX MM
When I try to connect on of the fibers to either trunk 2/1 or 2/2 nothing happens and stays in "standby mode". Is this right or do you think the uplink may be bad? More info below to support the topology:
sh mod
Mod Slot Ports Module-Type Model Sub Status
1 1 2 100BaseFX MMF Supervisor WS-X5530 yes ok
2 2 2 100BaseFX MMF Supervisor WS-X5530 yes standby

Sw : 5.5(20)
WS-F5521 015450793 Hw : 2.0
WS-U5533 022353263 Hw : 1.0
I get this error when trying to put into channel mode too:
set port channel 2/1-2 mode desirable non-silent
"Failed to set port(s) 2/1-2 channel mode to desirable"
Images later than 4.3 on cat 5500 puts the uplink ports on the redundent sup as inactive.You have to enable those ports on the sup to become active and use as normal uplink ports. run " set standbyports enable " on the sup and you redundent uplink ports will become active and can be used.
You migh want to see the ports support Ether-channeling or not so just run the command " show port capabilities 2/1 or 2/2 " and will tell you the status.

ASA 5505 Trunking problem with cisco 3760
Here is my asa 5505 configuration and at bottom i am pasting cisco 3760 configuration, I am having trunking problem and seen other people having the same issue but no solution.
Problem: when i connect any device on Switch 3760 port 1 which is trunked i cannot communicate with niether vlan.
I have tried device with both static vlan configuration
192.168.1.99 (vlan 2)
172.168.1.99 (vlan 8)
if i change port 1 to access mode or define native vlan it work with one vlan.
interface 5 of Cisco ASA is connected with interface 25 (uplink) on Cisco Switch

Message was edited by: macboyHello,
I can see many people have visited the post but there isn't any reply.
I think this is because of the following:
The configurations are long and most people dont want to read it. Try adding only relevant configuration to the issue.
The problem description is not clear. You mention trunking problem but what exactly is the problem? Can you ping from switch to ASA? Is any Vlan information being passed or they are all failing. Try to be as much specific as possible.
Which port of the switch connects to the ASA?
Using portfast on a trunk (interface GigabitEthernet1/0/1) is not recommended.

Felipe.

Router 2811 and C2960 Switch Trunking Problem
Hi all
I got an problem with a trunking problem between Router 2811 and C2960 switch
In router 2811 - I created f0/0.1 10.65.20.1 (VLAN 1) and f0/0.48 10.65.23.1 (VLAN 48)

Route pattern to SIP trunk problem
Hello, I have a 2801 router that has been configured with CME and a working SIP connection to my local ISP.
Tested with calls via CME so I know for sure that the SIP config and dial plan is fine on this gateway.
Next I wanted to try out CUCM so I set up a CUCM 8.6 box that is connected to the 2801 router to use as it's SIP gateway.
The only change I made to the gateway router config was to alter the "ip option 150" address so that the phones go to CUCM for their configs etc (which they do with no problems).
Then I set up a SIP trunk in CUCM along with a route pattern which is to use the SIP trunk within the Gateway/Route list option.
But when I make a call that matches this route pattern all I get is the intermittent beep message from the phone. I cannot route calls succesfully through it.
I have checked network connectivity and all is fine. The IP address I specfied in CUCM for the SIP trunk is simply one of the interfaces on the 2801 router and it is definitley reachable.
I also activated "debug ccsip all" on the 2801 gateway router but nothing appears. So it seems like the calls are not even reaching the 2801 gateway ?
Is the problem possibly a conflit between CME on the gateway router and my CUCM ?
Do I need to disable CME somehow on the gateway first ? Or am I not doing something correct in the CUCM config ?
Thank you kindly for any suggestions.
ps. I have attached a couple of screenshots of my config.Hello, thanks for helping.
I activated "debug voice ccapi inout" as well as "debug ccsip all" on the gateway but nothing showed up.
Therefore I deduce the call is not even making it to across the SIP trunk into the gateway router ?
As I am a newbie trying this out for the first time, it is guranteed to be something really simple.
I have included my running config from the gateway router below..
One addition I made was to add an incoming dial peer. That is "dial peer 5, description CUCM SIP trunk".
I set it up with a destination patter 2... to match my phone config on CUCM which have numbering in the 2000 range.
Sorry, I got RTMT up and running but could not get any meaningful results from it. I need to learn up on that.
I did however run a 'dialed number analysis' from CUCM direct and have attached the result. It seems the dialled number "99" is matching the route pattern OK.
So why is it not then moving down the SIP trunk to my gateway and getting picked up by the incoming dial peer ?
Thanks if you guys can offer any more help.

I have an analog trunk plugged into a 2811 with a VIC2-4FXO. When the line is in use, if a call comes in on it, the caller hears one ring, then a busy signal (not just a busy signal). What would be causing this? It happens to be the last line in a hunt group that is set at the CO to forward on busy to another hunt group, but the forward isn't happening, probably because of that first ringback.
Likely the problem is not due to the router. If you do "debug vpm signal" you will see the incoming ring and port going off-hook. You should see that for engaged ports, no new call is presented, and is the router does nothing in generating ringback, as you said the line is busy already when the call comes in.
hope this helps, please rate post if it does! -
HI, I installed the UC320 for a customer and they have 19 users, we are using sip trunk for voice traffic
it now encountered an annoying problem, The isp is doing the maintenance in recent period and their sip trunk is coming down and up occasionally at night. Whenever the sip trunk broke and come up again, the UC320 seems loss the sync with the wan, and it can work for 1 or 2 days and then the phone can not dial externally and also the incoming call have the problem, Yet the internal call is ok, whenever, this happened, we need to restart the uc320 to resume the service. I configured the auto maintainance happen at Sunday morning 3am , yet, there are times that the sip trunk broke happen on Monday night, then we usually get the complaint from the custom around Wed. or Thurs. and then we had to restart the system to resume the service. It is really troublesome. Do you have any idea how to deal with the problem. Is it a bug of cisco uc320? Is there any software update or any patch for this problem?
We are running 2.3.2(6) now.HI
Thank you for your reply, but the thing seems a bit more complex, our network configured as unregistered by the requirement of isp, and it works nicely. when the sip broke down and come up again, the pbx can work normally for 1 or two days and then it seems drifted away. and the problem at beginning is minor with only a few phones malfunction, and can be retored by restart the phone, but as the time goes by , the problems seemd deteriorated until all phones not working and we have to restart the pbx.
I check the external trunks, the status of sip is unregistered. it is required by isp to be configured so. it works nicely as long as the sip trunk is on.

Unified communication sip trunk problem after modifying topology
hi all
i have UC and its fine and sip trunk is ok
the toplogy is as below
UC------------------internet
now im going to add ASA with UC with new topology
UC-------------ASA-------------internet
the pbx internally is ok , but sip trunk is not working
pbx now have private ip and it can reach internet
the problem is sip trunks is not working !!!!
i will post the config of UC when its connected to Internet direcly and wish to help me why the 2nd topoloy no sip trunks working ?!!
do i need to do portforward ??
anyway here the config when sip trunks works and when UC directly to internetTry disabling SIP inspection on the ASA

I have a network design issue to solve and need some help. Current network uses ISL to trunk vlans between two sites. Some encryption devices need to be installed that do not understand ISL (or BPDUs for that matter). I need to split the ISL, or tunnel it, so that the inside devices cannot see the L2 stuff but the end devices can still communicate. Any ideas?
Regards ... JohnHi Josh
I had to solve a very similar problem to yours, and the solution I came up with was to use L2TPv3 (layer 2 tunnelling protocol) over IPSEC. I used the same device (a pair of old 1700 series routers at each end) to create both the L2 tunnel and the IPSEC tunnel, but in your case you are using a separate device to do the encryption. You just need to create the L2 tunnel between 2 devices which are on the unencrypted side at each end. You need to ensure that the 2 devices can route to each other. -
I have a trunk (Non-gatekeeper) between the legacy CCM 4.12 system and the new CCM 6.0. The trunk on the CCM 4 has the SUB then PUB listed, same on the CCM 6 side. Calls flow from the CCM 4 side to CCM 6 side no problem. Calls do not work from the CCM 6 to the CCM 4. Now here is the interesting part. This was working when I only had the PUB running on the CCM 6 side. I just added the SUB. So, I changed the server group to have the SUB listed first and moved the PUB to second. But I have updated the trunk config to match. But if I move the PUB up in the list and leave everything else the same and do a reset everything starts working again.
I have the same problem with the ICT.
from a single CCM 6.0 to a 4.2 cluster works fine, but not the other way.
Do you resolved your problem?If yes what you changed? -
Two switches connected with fiber in mode trunk - Problem
Hi to all.
Iam new in the forum, and my english is bad.
I want to post a problem. I have two switches connected with fiber in mode trunk, in the switch C3550 i have this configuration:
interface FastEthernet0/1
description Enlace LAB Medicion
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
duplex full
spanning-tree portfast
In the switch C2960 this configuration, on interfaces Fa0/48, Giga0/1:
interface FastEthernet0/48
switchport trunk allowed vlan 1,20,229
switchport mode trunk
spanning-tree portfast
interface GigabitEthernet0/1
switchport trunk allowed vlan 1,20,229
switchport mode trunk
media-type sfp
duplex full
spanning-tree portfast
The problem:
The ip phones with Voice vlan (vlan 20), not find the DHCP server located in the data vlan (vlan 229)
However, using the command:
#switchport trunk native vlan 229
The result is the voice vlan works, but the data vlan not and viceversa depending if the native vlan 229 is present.
I will appreciate any suggestion.leolaohoo.
The configuration on ports switch C2960, have the mode access with voice vlan 20:
interface FastEthernet0/1
switchport access vlan 229
switchport mode access
switchport voice vlan 20
spanning-tree portfast
interface FastEthernet0/2
switchport access vlan 229
switchport mode access
switchport voice vlan 20
spanning-tree portfast
I will remove from trunk links:
spanning-tree portfast
Thanks alot. -

Administrative private-vlan trunk associations: none
Administrative private-vlan trunk mappings: none
Operational private-vlan: none
Trunking VLANs Enabled: 10,20,30,40
Pruning VLANs Enabled: 2-1001
Capture Mode Disabled
Then lastly on switch 2 I created a port for an Ubiquiti access point with following settings.
interface GigabitEthernet1/0/24
switchport trunk native vlan 10
switchport trunk allowed vlan 10,20,30,40
switchport mode trunk
end
But my AP doesn't seem the get an IP. Where as if I plug it in on Switch 1 it does with the same settings.
So I am assuming there is something wrong with my trunk. What am I doing wrong?
Thank you,
MichaelHere are a couple of observations:
1. The switchport trunk encap dot1q command was not applied on the 2960 because 802.1q trunking is the default. The 2960 series switches do not support ISL encapsulation, as the OP observed. There is, therefore, no need to manually specify the trunking protocol. The show int g1/0/24 switchport command confirmed that trunking is working. I find the show int g1/0/24 trunk command to be more informative in this context. It tells you what VLANs are active and trunking between the connection.
2. You do need to define VLANS 2-30 on your second switch. You can do so manually or you can configure VLAN Trunking Protocol (VTP). VTP is your easiest bet. Example config:
Switch 1
sw1(config)# vtp mode server
sw1(config)# vtp version 2
sw1(config)# vtp domain MY_DOMAIN
sw1(config)# vtp password MySecret
Issue a show vtp status in priv exce mode to very your settings.
Switch 2
sw2# show vtp status
Do this command FIRST and make sure that the configuration revision number is smaller than the revision number of SW1.
VTP Operating Mode : Client
Maximum VLANs supported locally : 255
Number of existing VLANs : 25
Configuration Revision : 174
If config revision on SW2 is greater than config revision of SW1, then issue following command:
SW2(config)# vtp domain bogus
SW2(config)# vtp domain MY_Domain
SW2(config)# do show vtp status
Your config revision should go back to zero.
Now issue the same commands on SW2.
SW2(config)# vtp version 2 (pretty sure that is default, but I issue it anyway)
SW2(config)# vtp mode client (means you cannot define VLANs on this switch. Most admins prefer that only one switch be capable of creating VLANs).
SW2(config)# do sh vtp status
The config revision was important because injecting a switch into your network that has a higher VTP revision can overwrite your existing VLAN database. If that happens, chances are that most of your network traffic will cease to function as all of your access ports will be in a VLAN mismatch mode. -
Catalyst Express 500 series trunking problem
We have a cisco 2801 router and CExpress500 switch. The router is connected to switch over the port role "switch" and native vlan no is 1. The router is configured as this:
interface FastEthernet0/0
no ip address
duplex auto
speed auto
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 192.168.110.4 255.255.255.0
no snmp trap link-status
interface FastEthernet0/0.184
description vlan184
encapsulation dot1Q 184
ip address 192.168.184.1 255.255.255.0
no snmp trap link-status
Users can reach the native vlan but they cant reach other vlan. Any comment?The port on the CE500 should be set as a router, otherwise DHCP from/through the router will not work. Setting the port as "trunking" is not possible on a CE500 switch; you must choose predefined smartport types.
Set up your router port as a Dot1Q interface with sub-interfaces and make sure the native VLAN matches on both devices. -
CUCM 10.5.1 and Exchange 2010 Unified Messaging (UM) SIP Trunk Problem
This is more a comment if you're migrating from a lower version to 10.x. Hopefully Google will pickup this post so others don't spend too much time (I got lucky and found this in about 30 minutes).
There are many more SIP options than in the past. If you configured your integration as per the integration doc, all settings are relevant, however there are some new defaults that need to change.
SYMPTOM: Dialing another number or AA pilot and being redirected internally works, but the call drops on calls from external phones. Exchange logs an Event ID 1079 from UMCore and also informational 1084 and 1172 events. A capture yields a status 200 OK, then an ACK, two BYEs and a status 481 that the call leg does not exist. The call is then dropped.
RESOLUTION:
In the SIP Trunk, modifiy the following:
Device Information. . . Check Media Termination Point Required. I've had some that have needed this checked and some where I needed to leave unchecked. In this case going from 7.1 to 10.5 necessitated enabling.
Call Routing Information. . . SIP Privacy: Need to change from Default to None.
Any comments how the SIP Privacy might affect security and functionality would be appreciated.Just to inform everyone. I rebuilt the edge server from scratch.
Now everything is working as expected.
I cannot work out how the edge was not passing on calls to exchange or not communicating correctly with exchange.
Anyway it is resolved now. -
Trunk Problems Between 3500/2950
Hi All,
am trying to create a trunk between a 2950 and 3500. I did the following,
2950:
swsales1(config)#int fasteth0/12
swsales1(config-if)#switchport trunk allowed vlan 1,2,3
swsales1(config-if)#switchport mode trunk
3500:
Ted(config)#int fasteth0/12
Ted(config-if)#switchport trunk allowed vlan 1,2,3
Ted(config-if)#switchport mode trunk
I get the following error on the 3500,
swsales1#
00:14:14: %LINK-4-ERROR: FastEthernet0/12 is experiencing errors
vtp domain for both is the same and the 3500 is the client. Cross-cable between the 2 ports. Cheers.
EDIT: no shutdown was issued on both interfaces.
coolboarderguy...Hi All,
funny you should mention the switchport nonegotiate command, as neither switch would accept it. I found it strange, as this lab,

uses it and the lab states that it used 2950 and 3500(3550) switches. Cheers.

Nexus fport-channel-trunk problem
I have a Nexus 5548UP running 5.0(3)N2(1) and I want to enable the fport-channel-trunk command but I cannot enable this feature. When I issue a show feature I see it as a disabled feature but I cannot turn this on. I want to enable this so I can set up an F-Port Channel to a Fabric Interconnect 6120 (UCS).
I have enabled the following features
feature fcoe
system default switchport trunk mode off
feature telnet
cfs ipv4 distribute
cfs eth distribute
feature lacp
feature vpc
feature lldp
feature npv
feature npiv
I am also running the following licenses

Any help would be usefulYour N5k is configured to be in NPV mode and hence fport-channel-trunk is not a feature you can configure. However, the NP ports on the NPV switch can be bound into a channel/trunk to a NPIV/core switch which has
fport-channel-trunk configured.
