Cisco Switching/Routing :: Port Error Disabled On N7K-M132XP-12L Module

May 20, 2013

I've got a pair of N7010's in a vPC domain with some FEX's attach running NX-OS 6.0.2. I am experiencing port failures on my N7K-M132XP-12L module the port got shut down due to internal errors with Error Disabled status and I am not able to bring the port back up. I am getting the following errors when I try to reset it. I am hoping is not hardware related as my vPC peer-link is on this module and I only have a single N7K-M1 32 XP-12L in each N7010. Replacing the module will be painful. [code]

Cisco Switching/Routing :: Nexus 7010N7K-M132XP-12 Queuing

Nov 6, 2011

NX-OS 5.0(3)N2(1)Nexus 7010N7K-M132XP-12 line cards.By default the linecards/system use only 2 egress queues for the 32 port M1 cards.
 
1p7q4t-out-pq1  (matches cos 5-7)1p7q4t-out-q-default  (matches cos 0-4)Which really doesn't line up with what wanted so we modify the config on the default vdc to the following.
class-map type queuing match-any 1p7q4t-out-pq1
match cos 5
class-map type queuing match-any 1p7q4t-out-q2
match cos 7
class-map type queuing match-any 1p7q4t-out-q3
[Code]....

By modifying the default queues it's affected the default egress  policy-map, and in order to function correctly, a custom default list  needs to be setup. With the default egress policy, anything not in the above 4 queues gets dropped.
 
Why doesn't the output queue in the default policy map (out-q3) match the actual class-map name of 1p7q4t-out-q3Are my assumptions about the output discards correct relating to the fact there is no relevant mapping for the modified egress queues in the default system policyWhere in the config guide is this? I've seen some reference that infer it, but don't actually point it out. Why this is a system wide config item, rather than on a per vdc basis.

Cisco Switching/Routing :: PoE Error On 6500 / Inline Power Module

Feb 12, 2012

Cisco IP phones attached to a Moduke in one of my Cat6500 access Switches suddenly went down. Upon closer  inspection of the Switch Sys log, I observed the following Sys log error messages:   [Module 9 is experiencing the following error: Inline Power Module - PS Voltage bad. ]A sh Mod output indicates the PoE daughter card and Main Module are "ok" - see attached output. It appears issue is related to the the actual Power Supply module and not the blade module and installed PoE Daughter card. I am inclined to open a TAC case for a PS replacement, but wanted to see if this can be resolved without a hardware replacement. At this time all 48 IP phones attached to this module are out of Service.

Cisco Switching/Routing :: 2811 With 16 Port Switch Module Configuration?

May 12, 2013

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
 
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.

Cisco Switching/Routing :: 4500 24-port Gigabit Module Being Picky

Jan 7, 2013

We have recently purchased a Cisco 4506 that has several Gigabit Ethernet modules installed.One of the Ethernet Gigabit modules - a WS-X4424-GB-RJ45 - is being picky with who it talks to at Gigabit Ethernet.
 
If I plug a laptop into one of it's RJ45 ports using a Cat 6 cable, nothing happens.  No link light, no notification of link up or down on port statistics, absolutely nothing.If I plug a server into the same port it works fine at Gigabit Ethernet (even using the same Cat 6 cable).I can get the module to recognize a laptop if I fix the speed/duplex on the laptop to 100Mb/Full. I have tried this with other staff laptops from different vendors (HP / Dell / etc.) all with the same result.
 
The module directly underneath this module - a WS-X4448-GB-RJ45 - works fine for both laptops and servers.  We have tried swapping the module positions but to no avail.

Cisco Switching/Routing :: 6509 / WS-X6704-10GE Module And Port Status?

Dec 7, 2011

We have two 6509 switches with one WS-X6704-10GE module in each of them. There is an optical cable between the two switches plugged in  WS-X6704-10GE module on both sides. When you shut down the port on one side the other port still stays as up and you need phisycally to unplug the cable to have it down. The same behaviour is seen no matter on which of the two switches you shut down the port, the opposite one always stays as up and only removal of the cable makes it go down.
 
The ports are configured quite simply:
 
interface TenGigabitEthernet1/1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-10
no ip address
udld port
 
The IOS version is 12.2(18)SXF8

Cisco Switching/Routing :: 3925 With 48 Port Switch Module Infinite Loop

I have a 3925 Router with a 48 port switch module (part number SM-D-ES3G-48-P).  I have no problem accessing the 3925 Router, but when I go into the 48 port, I get an error that reads
 
Error Hardware not supported by firmware. Try loading a newer software instead. System Resetting...
 
I know that the wrong IOS is installed on the switch, but the problem is that this is an endless loop.  The switch resets then comes back to the same error.  How to get the switch out of this loop so that I can load the correct IOS.

Cisco Switching/Routing :: Configuring 1941 With 8 Port EHWic Switch Module And Onboard GE Ports In Single LAN?

Jul 1, 2012

Can you configure a Cisco 1941 to use an 8 port EHWic module and the 2 onboard GE ports in a single LAN?

I've discovered you can't have the on GE ports associated with a VLan, and I'm when I've previously researched for a solution, bridging was mentioned but I cannot seem to get it to work (or completely understand it)The reason I would like to use all 10 ports on for the LAN is becuase I have 10 devices I need to connect to the 1941?

Cisco Switching/Routing :: Port Goes Into Error Disable State 3750

For example if I plug PC A to the phone that connects to port 13 I pick up an IP addressand all works as predicted now if I plug in PC A to any other VOIP phone that connect to another port on the same switch it goes in error disable state ITs like the switch is holding my PC mac address and locks it down with the port which in my case is Gi2/0/13.

Cisco Switching/Routing :: 3750G Found Duplicate Mac-address Error / Not On More Than 1 Port

May 11, 2010

I've run in to this on 3750G's in a various sized stacks. We apply port security for a mac address on a single port (not existing on more than one port - that's  a different issue that appears in multiple posts already).In this case:
 
1) We do a 'sho mac address-table and see that the device with the mac address in question lives on one port, port 1/0/x.
 
2) We apply mac port security for this exact same mac address to the same port it is already attached to. switch(config)#int g2/0/2 switch(config-if)#switchport  port-security mac-address 001a.1ec8.abcd
 
3) Get this error: 'Found duplicate mac-address 001a.1ec8.abcd'.We again confirm that that is the only port on the entire switch that has this mac-address.Try the command again, same error.
 
4) We do a bunch of show commands, get in and out of the switch, go back and then try it again, and now it works, same command, same port and same mac address.
 
-Aging is default 300
-These are Cisco wireless AP's attached to the switch
-This occurs on different switches with different ports using different mac addresses, always same symptoms.

Cisco Switching/Routing :: Catalyst 2900 XL Console Access Disabled

Jun 30, 2012

I just purchased a used Catalyst 2900 XL switch and have not been succesful in connecting to the console via minicom 2.5 running on Ubuntu 12.04 or 11.10, I don’t even get junk charecters in the terminal or echo on input. The switch passes POST according to the LEDs on the front and the network ports are fucntional for switching purpouses.
 
I’m using a Prolific PL2303 USB-Serial adapter, which works with minicom to console into another device.  I’ve tried every baud rate available and tried combonations of hardware flow control, software flow control, and niether.I’ve tested the pinout of the console cable and all pins map correctly according to Cisco spec.I’ve also tried Cutecom, putty, and screen. I have not tried HyperTerminal because I do not use windows.Is it possible that the previous owner disabled console access? Do I need to reboot the switch each time I test a different baud rate?
