Cisco :: Terminal Monitor Command Not Showing Debug Output?
Feb 22, 2011
What would cause debug output to not show on a remote session via telnet connection where you've enabled terminal monitor?
The reason I ask is I was working with a client and we were debugging WCCP. I ran the debug ip wccp packets and events commands, then entered terminal monitor. After this, we saw nothing. We should have at least seen particular WCCP-related packets because we saw the necessary cluster view was established which can't be done without the exchange of these packets.
Can having syslog (logging) configured cause the issue? Did I use the command incorrectly?

I am runing 802.1x and MAB authentication of devices connected to a 3560 switch (in test). When I run 'terminal monitor' I am getting alot of authentication fail-msg. Is it possible to get the switch not to show them? I have to do some debugging on SNMP and DHCP to be able to figure out why I get these msg, but since the switch is blasting out so many auth-msg it is hard to see the debug messages. [code]

I plug both the monitors to another VCD it works fine and if I've tested the VGA cables on both monitors and that is good as well. I was assuming it might be a monitor format issue so I tried to access the Monitor format option from the KBD5000 but it does not give me an option to change the format, I just have three buttons when I click on the Monitor Icon

I faced with strange behavior of Cisco 2901.I strat ospf process on router, do some ospf manipulations and than turn off ospf with
R1(config)#no router ospf 1
But after that when I start to change my config: shut/no shut interfaces I see OSPF debug messages
R1(config-fr-dlci)#interface Serial0/0/0.5 point-to-point
R1(config-subif)#sh
R1(config-subif)#
Jul 5 12:33:13.004: OSPF EVENT Se0/0/0.5: Route adjust
R1(config-subif)#
R1(config-subif)#
R1#sh
Jul 5 12:34:15.076: %SYS-5-CONFIG_I: Configured from console by consoleip pro
R1#sh ip protocols
*** IP Routing is NSF aware ***
How it can be? Thereis no OPSF process on R1.

Debug is not showing up on the console. I have configured logging console. My older switches, if an interface goes down or is brought up, it shows up on the console, but not on the new 4507s.

I use a C892 router with the IOS c890-universalk9-mz.152-1.T.bin. I just ran the command "debug ip packet 151 detail" and then the router stopped to work because it was overloaded. The ACL151 I used is as follow:
Extended IP access list 151
10 permit ip host 10.1.1.1 host 91.1.1.1
In the syslog then I got hundred of messages from IPSec:
Jan 11 09:43:35.677: IP: s=10.80.10.254, d=10.64.19.99, pak 8A7453CC consumed in output feature , packet consumed, IPSec: to crypto engine(70), rtype 1, forus FALSE, sendself FALSE, mtu 0, fwdchk FALSE
[code]....
For me it seems just like that this ACL is not applied and that I have a debug then for the whole traffic.

We are experiencing intermittent issues with the IPS on our ASA5585 vs 8.4(2). Probably something with the dataplane. So I want to keep debug cplane 255 activated and logged with log debug-trace setting to syslog server. But when session times out the debug command is cleared so the output stops. Since it is a intermittent issue I want to keep debug activated...Totally different behaviour then with routers which keeps it activated. how to keep debug activated on a ASA.

My Nexus is a 5548-UP model, NX-OS version : 5.1(3)N2(1b)
I try to debug an OSPF and an ICMP problem using the debug ip ospf command and the debug icmp command but not output appear on the terminal. As the switch is remote, I entered the terminal monitor command of course.
SG01NX01# terminal monitor
SG01NX01# debug ip ospf 1 packets
SG01NX01# show debug

I have copied status codes from show ip bg command output and its explanation (from Cisco documentation site)., d and h (suppressed, dampened and history). I read somewhere that these are to control flapping routes. But not able to understand it completly.Raised this question in a couple of forums but didnt get a proper reply.The table entry is suppressed.??The table entry is dampened. ??The table entry history. The table entry is validThe table entry is the best entry to use for that network.

How do you save the command output from the CLI to a file on flash?
With IOS, I would normally use a pipe command to redirect to tftp, but the ASA doesn't support this as far as I can tell. As a work around I was thinking I could save the output to flash and then tftp that file off the ASA.

We have an ASA 5540 failover bundle working in Active/Standby mode. On our active asa 5540 when the sh run command is issued it gets stuck and displays the output after more than 15-20 mins.. and it takes another 10-15 mins to get back to the prompt..
However on the standby asa 5540 if the sh run command is issued, it displays the ouput and comes back to the prompt (even though this also takes 2-3 seconds)
I have tried rebooting the active asa 5540.We are running asa version 8.2.2.

=>Routing Protocol in Question EIGRP.
=>Two equal metric routes for destination A(through R1 and R2-SVIs on two upstream 6500s)
Traceroute Output, is the output that alternates between 1.1=>10.1=>1.1 normal granted the two routes are "equal metric routes for the same routing procotol in use" or is that "round robin behavior" indicative of a routing problem?

I have 1x Cisco 6509 with Sup2 and MSFC2 and it is running on IOS (c6k222-jk9sv-mz.122-17d.SXB11). I have following policy map :
Policy Map VOIP
Class IP PHONE
priority percent 75
and the following command on each interface: service-policy output VOIP those configuration are working fine on SUP2 with MSFC2 but last week I tried to upgrade the SUP2 to SUP32 on the switch and upgrade the IOS to the latest version (s3223-adventerprisek9-mz.122-33.SXJ4) but when I try to put service-policy output VOIP on each physical interface I am getting the following error:
"Priority command is not supported in output direction for this interface" and when I try to add service-policy output VOIP on a V LAN interface I am getting following error:
MQC features are not supported in output direction for this interface. Will I need to change something after upgrading to SUP32..

I have been using "debug ip packet" on a Cisco 2921 running IOS 15.1(4)M1. The problem I have is that, although I am using an ACL to limit the output, I am seeing some output that is distracting from what I am trying to see. Specifically, I am seeing the following:
Mar 19 20:22:36.135: IP: s=192.168.20.253, d=224.0.0.2, pak 30DB6D4C consumed in input feature , packet consumed, MCI Check(80), rtype 0, forus FALSE, sendself FALSE, mtu 0, fwdchk FALSE
[ code]...
These would appear to be HSRP messages. But I don't understand why they are appearing when I configure "debug ip packet 101". The ACL is pretty simple:
access-list 101 permit icmp host 96.87.145.1 host 192.168.20.1
access-list 101 permit icmp host 192.168.20.1 host 96.87.145.1
So I thought the implicit "deny ip any any" would block these messages. I even tried to block them specifically using an extra line:
access-list 101 deny udp host 192.168.20.253 host 224.0.0.2 eq 1985
But still they show up!

Using 'debug ip packet acl# det on a 2911. On an older Cisco router you could set up an ACL
access-list 150 permit tcp any any eq 1023 and then run debug ip packet 151 det and this would give a good debug output for any traffic matching a TCP port of 1023.Now when I try this on a 29xx ( Version 15.1(4)M3 ) I get the screen filling with a lot of multicats HSRP communications.
I have tried rewriting the acl to have other deny statements after the permit to limit the source or destination hosts and/or the ports but the HSRP data is still there.
like this
access-list 150 permit tcp any any eq 1023
access-list 150 deny udp any any eq 1985(code)

how to debug an ACL I've created on a 4404 WLC, specifically I want to monitor what packets are being denied by the ACL as something that should be working isn't
I've created an explicit deny statement at the end of the ACL and verified that the counter increases each time I try the problem software update.
What I can't work out is how to get the WLC to tell me what packets are being denied by the explicit deny statement, all I can find are 'show acl' commands which just give me the counts.
The equivalent on a router would be debug ip packet acl and adding the log keyword onto an ACE. I suppose I could configure a SPAN session on the WLC uplink to the switch but that seems overkill?

Iam fairly new to Cisco IOS and am having trouble getting an IPSEC tunnel to come up between 2 cisco 881-s. I have entered both debug crypto isakmp and debug crypto verbose but when I try to ping an internal IP at the other location through my VLAN1 interface no debugging info comes up.
Also my ACL-s for the crypto maps show no activity. I have tried many things so my configuration files are starting to get really messy.

I'm troubleshooting one way audio with our anyconnect phones.I think it is a routing issue.typically I wouldnt run debug ip packet detail on a production router, however I just found out that you can use acl's to specify the traffic to be debugged.
R1(config)#access-list 199 permit tcp host 10.1.1.1 host 172.16.1.1
R1(config)#access-list 199 permit tcp host 172.16.1.1 host 10.1.1.1
R1(config)#end
R1#debug ip packet 199 detail
IP packet debugging is on (detailed) for access list 199
The use of debug commands requires the allocation of system resources like memory and processing power and in extreme situations can cause a heavily-loaded system to stall. Use debug commands with care. Use an ACL in order to selectively define the traffic that needs to be examined to reduce the impact of the debug command. Such a configuration does not filter any packets.

Any way of narrowing down a degub for a peer address only? For example, I currently run 'debug crypto isakmp 127' which captures everything, but can I run the same dVPN debug for peer address 1.1.1.1?I know you can run 'sh crypto ipsec sa peer 1.1.1.1'.We're using an ASA5520 (8.4.2).

I am quite new to wireless side and had a small Q regarding watching debug output while i am ssh to the WLC? I tried the other day and did not see any messages, now this could be for the reason that nothing triggered or perhaps it needs something like terminal monitor?? i couldnt find any such command. my WLC is 5508 running 7.3 version.
