Cisco Switching/Routing :: Interface Showing Inactive On Cat4500?
Jan 22, 2013
We have 3 Cat 4500 switches on three floors teh 3rd floor switch connects to the 2nd and 4th floor switches ,but we are receiving an alert from monitoring tool that " Interface(314) Backup-1Gb-Ring is Down at least 2 min on Switch: SOM500-4510-3FL the following output from "sh int status module 1 " shows the int 1/3 and 1/4 are 'inactive'local IT guy said If the status is inactive,the ports cannot be used and might lost the capability when he added 48-port blade into the 10th slot.

I always though that sh mac address table dynamic interface xx/xx/xx was a subset of "sh mac address table" 6590 Version 12.2(33)SXI I have two mac addresses on downstream switches that will only show up when using
sh mac address-table dynamic interface Te4/10
* 903 0050.77a9.6e3c dynamic Yes 0 Te4/10
* 903 0050.77a9.5766 dynamic Yes 0 Te4/10
when using "old faithful"
sh mac address-table | inc 6e3c
*nothing*
or
sh mac address-table dynamic | inc 6e3c
*nothing*
nothing shows up?this vlan has no layer three interfaces

I am trying to configure a 4507 R chassis with Dual SUP but i cannot see teh switchpot mode trunk encapsulation dot1q?
I have typed:
interface GigabitEthernet5/1
description DOWNLINK toxxxxxx
switchport mode trunk
channel-group 11 mode on
!
I have have searched all other commands and sub-commands but could only find dot1q-tunnel which I beleive is for QINQ or some QoS featues and lot for L2 encapsulations?
the puzzling is:
XXX-Core4507#sh int gi5/1 trunk
Port Mode Encapsulation Status Native vlan
Gi5/1 off 802.1q notrnk-bndl 1
(Po11)
when I connect the dostribution switch a 3507 to this int gi 5/1, both interfaces do come up?

I'm currently working on a plan to migrate our 6500's over to our new 7010's. At the time of the migration I want to tighten up our OSPF design and configure OSPF for "passive-interface default" then allow only those interfaces that should have OSPF neighbors to send the hellos. The issue is that the command is not showing up under the OSPF process. What's even more interesting is that the Nexus 5.x Unicast Routing Configuration Guide shows that the "passive-interface default" command should be an option to enter.
I'm currently running version 5.1(4) (though looking to upgrade to 5.2 during my migration testing). I would rather configure the passive-interface via the routing process versus having to enter it on every interface.

OK so I am following the steps that i got from off the CISCO site on upgrading the IOS, when i get the the part where if says to:
redundancy reload peer
so after i do that i go to the standby supervisor and i see that it is in a continuous reboot loop. I stop the loop and i reload the sup to the original IOS cat4000-i9s.........
SO i look at the logs and this is what i see:
Aug 12 22:21:01.251: %C4K_REDUNDANCY-6-INIT: STANDBY:Initializing as STANDBY Supervisor
*Aug 12 22:21:03.259: %CHKPT-3-IPCSESSION: STANDBY:Unable to open an IPC

I have a 4503-e with WS-X4013+TS supervisor and WS-X4548-GB-RJ45 card. I purchased a WS-X4648-RJ45-E card and installed but IOS says its unsupported. Supervisor is running 12.2(46)SG software and 12.2(31r)SGA firmware. Obviously I'm hoping this cars can be supported somehow. Do I need to upgrade software or firmware, or return the linecard and get equivalent supported card? Oh, system is running Catalyst 4500 L3 Switch Software. (cat4500-IPBASEK9-M)

In testlab we use pim-sm with bootstrap router on sup7 with IOS-XE 03.04.00.SG. Any possibility to prevent non authorized rp from connecting to the candidate bootstrap routers? We found several security recommendations concerning limiting registering of sources at the rp, rate-limits etc, but no possibility to control rp connecting to the bsr.

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?

For an assignment in a class I am taking I created a simple network using GNS3 and set up static routing. Everything works fine, I can ping all of the hosts. One of the questions I am supposed to fill out is what happens when I use the "show ip route" and "show ip protocols" commands. When I use "show ip route" I get what seems to be the correct output. However when I use the "show ip protocols" command nothing happens. No output, no error, no nothing. It just goes right back to the prompt. This happens exactly the same on both routers in my network. incase it matters the router is c3640.
PS. would the output be non-existent because I have not set up any ip protocols. In a similar assignment I set up rip and when I used "show ip protocols" i did get what appeared to be the correct output. However I didn't write it down and when I put in the command again about an hour later after I took a break I also did not get an output until I re-entered the rip related commands.

We ordered the wrong part number for a Cisco 4506 non-E chassis, the part number is: WS-X4624-SFP-E and the device is showing "Unsupported module"; What would the part number be for the non-E? WS-X4448-GB-SFP,Catalyst 4500 48-Port 1000Base-X (SFPs Optional) ?

I have configured the following access-list on routers fa0 interface (i am using 1801)
access-list 111 permit ip any any log
and applied it in "in" direction on Fa0 interface.
Now when i am sending ssh packets to this interface its showing below
*May 14 05:09:00.104: %SEC-6-IPACCESSLOGP: list 111 permitted tcp 172.18.128.2(0) -> 172.18.128.146(0), 1 packet
why its not showing any port number ?

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]

Looking at the following output (show interface status) from one of our 4507s I see gig interfaces 3/2 to 3/6 are all trunked (dot1q). When I look at a show run they do not show as trunked. They should indicate switchport trunk encapsulation dot1q and switchport mode trunk (as does interface gig4/2). I have seven other 4507s all running the same IOS: 12.2(25)EWA8 and they all show the same information in show run and show interface status (as far as trunked goes). This is not a problem as I know the interfaces are trunked and working properly I am just puzzled as to why I see this difference.
Here is the sho int gig3/2 trunk. It looks like you are correct. I did not realize some were set to trunk mode on and others were not. I would think the running config would still show the port using dot1q but I guess not.

We have several stacks of 3750 switches where this problem is occurring. All of the switches are running IOS version 12.2(50)SE3. (Yes, I know it's old.)
We're seeing inconsistency in how the stack reports members when issuing the following commands:
sow switch
show version
show inventory
Not all members are showing up in the output of the "show version" and "show inventory" commands. For example:
HUNTI-WV-WDAC03#sh switch
H/W Current
Switch# Role Mac Address Priority Version State
----------------------------------------------------------
1 Member 108c.cff2.ea00 15 0 Ready
2 Member 8cb6.4f0a.a600 1 0 Ready
*3 Master 8cb6.4f0a.9c00 1 0 Ready
(all three switches in stack are displayed)(code)

I have couple of SFP and most of them are working fine except this:-
Nexus7000# show interface ethernet 6/31 transceiver details
[code]...
a) What is the reason this is not getting recognized?
b) Is theSFP SFBR-5766PZ-CS1 plug and play in the 7000 Nexus?

I have installed a Catalyst 2960-S and a 3750-X-12S and I am trying to setup a VLAN 51 for some VoIP phones. I have added the VLAN as an interface on both switches, but the 3750 is not showing VLAN 51 as active when i do a show vlan. Also, it omitts showing Gi1/0/1 & Gi1/0/3 which are uplinks to 2960-S switches plugged in and working on VLAN1.

I have having two Cisco 6509 both working are my main Core Switches with which I have all my Layer 2 VLANs configured and then distributed thru the trunks links to all the Access Switches. I have L3- Vlans also configured on them with which one switch in primary and the other is secondary. All of sudden last night I got this message on my core switch 2 this for VLAN 1 which is my users LAN, how can I check as to what would have caused the core switch 2 HSRP to be active and then in standby
*Nov 5 23:33:29.296: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Standby -> Active
*Nov 5 23:33:29.796: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Standby -> Active
*Nov 5 23:33:29.804: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Active -> Speak
*Nov 5 23:33:29.920: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Active -> Speak

*Nov 5 23:33:41.280: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Speak -> Standby
Also last night i got call from office saying that we are getting huge delay in pinging the default gateway of the user LAN which is the same vlan as the above and it was just for few minutes and then it was back to normal and now when I came to office and check there were no logs in both the core switches. When I checked the cpu utlization it was showing me high on both the switches how can I check as to what would have caused the CPU utilisation to go high all of suddedn?

I have reconfigured the FEX numbers attached to a Nexus 5548 running on NXOS5.2 If I do show running-config the interfaces are not there anymore. But if I do show startup-config the old Fex interfaces still shows up. I did try write erase then saved the running-config and its still there.
