Cisco Switching/Routing :: How To Debug A TCAM Switch On 877W

Feb 24, 2012

I've created a BVI2 where I bridged dot11 0.2 and vlan2 in order to have wired and wireless clients in the same vlan.Some wired client are not reachable from the lan. Wireless clients have no pbl in reaching each other.Monitoring a MAC address that is supposed to be behind the FA2 I have noticed that it moves to vlan2 when in fact it should be behind the FA2.Of course when "show mac-address-table" says it is behind Fa2 the ping to that MAC address works whereas when the TCAM reports it is behind vlan2 it doesn't. Once the MAC address is behind the vlan2 if I clear the mac-address-table and that mac-address is still put behinf Fa2 then the pings works again, sometime I have to perform twice the clear command before the MAC address goes back to the right location.I'd like to understand why the router moves that MAC address from Fa2 to vlan2 and that's the reason for my question in the subject.I don't have any problems for port Fa0 and Fa1."Show int fa2" doesn't show any problem/errors or the likes.BTW even if I force that MAC address to be statically behind FA2 the ping works fine but then stops and if I do "show mac-add" the static entry for it is still there... so looks like there us something that overrides that static entry. If clear everything and I have the mac-address be behind Fa2 then everything starts to work again. I used Fa3 instead of Fa2 and I get the same results.

Cisco Switching/Routing :: 3750E Debug Causes Switch To Crash And Reload

May 3, 2013

I am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error. Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.All the stacks (3 switches) are running 12.2(50)SE3, It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?

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.

Cisco Switching/Routing :: 6509 Debug Spanning-tree Functions In Lab

Nov 9, 2012

I'm testing debug spanning-tree functions in a lab, hardware is Cisco 6509 with SUP-720-3B and WS-X6748-SFP, IOS is 12.2.33.SXJ. It's a root in some vlan's, stp mode is rapid-pvst.I wanted to see how spanning-tree is working (STP packets dump, etc.), and entered following commands on 6509: [code]
 
Then, I turned the "debug spanning-tree all" mode on. Now, I expect to see BPDU packets from Cisco, and other spanning tree events in logs on syslog server, or in log buffer, but I don't get anyting there. Except, there're some lines in log (they repeat very rare): [code]

Cisco Switching/Routing :: IOS AAA And Telnet 1800 Configuration

Mar 1, 2012

I have aaa new model configured on a number of isr's(1800, 1900, 2900, 3800 etc).  When i have aaa configured, the telnet logins use that authentication and not the password in the line vty portion.  Is this by design.  would disabling aaa enable both telnet and aaa authentications, essentially making it a dual login.

Cisco Switching/Routing :: 1800 - How To Use Gateway On Separate Network

Sep 30, 2012

I've just started out playing with a Cisco 1800 router to gain some knowledge of Cisco devices before taking a CCNA. I also have a 2950 switch but will start with the router.
 
I'm using an Android phone as a wireless Internet access point.  This issues IP addresses by DHCP in the 192.168.43.x range with 255.255.255.0 subnet.
 
Also I have a Linksys WRT54G router running DD-WRT firmware acting as a wireless bridge to the Android phone, and it has 4 LAN ports.
 
This bridge is up and running and I have successfully connected my laptop to the Linksys for testing and can use the Internet provided by the phone.
 
Connected to the Linksys is a Cisco 1800 router. Connected to the router is my Citrix XenServer PC and a NAS box.
 
The XenServer and NAS are on another network 07.05.19.x range with 255.0.0.0 subnet using their own static IPs. One of the virtual clients on the XenServer will be a DHCP server to service other virtual clients.  All still in the 07.05.19.x range.
 
Basically I want the devices on the 07.05.19.x IP range to be able to use the Internet gateway at 192.168.43.1 to access the Internet.
 
How would I set up my 1800 to achieve this?
 
Also, am I right in understanding that the 1800 will ignore DHCP leases from the Android phone due to it being a Layer 3 device.

Cisco WAN :: Routing With 3 Public IP Net On 1800 Router

Nov 28, 2011

I don't know much about routers, but lately I've been playing around with router configuration and getting better but I am kind of stuck now.
 
The scenario is this.
 
I have 3 ip net from the ISP:
178.249.51.0/255.255.255.248 Gateway 178.249.51.1
178.249.51.8/255.255.255.248 Gateway 178.249.51.9
178.249.51.16/255.255.255.248 Gateway 178.249.51.17

[Code]....

I am also wondering - when we get more public IP net from the ISP, is this the correct way to do it?

Cisco Switching/Routing :: 3750 - Error Message While IOS Upgrade

Jan 6, 2013

Have a small stack of two 3750 routers.  Get the following error message every few secounds:
 
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
 
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
 
 Although when I try and copy a new IOS I get the following error:
 
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
 
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
 
Also I noticed there seems to be more than one flash directory. See below:
 
copy tftp: ?
  flash1:         Copy to flash1: file system
  flash2:         Copy to flash2: file system
  flash:          Copy to flash: file system
  null:           Copy to null: file system
  nvram:          Copy to nvram: file system
  running-config  Update (merge with) current system configuration
  startup-config  Copy to startup configuration
  system:         Copy to system: file system
  vb:             Copy to vb: file system
 
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?

It never happened before and the configuration did not change. The only thing that happened, the WAN connection (point-to-point to a Cisco 3845) went down and the router rebooted while the WAN was down. When the WAN came up again, everything went fine, until about an hour later and the first occurrence of this mentioned log.This 3945 does establish an IPSec tunnel with its peer (the 3845) and all the traffic, including OSPF, is going through the tunnel.
