Cisco Wireless :: 4402 - Data Path Down Control Path Up

May 5, 2010

have just set up a WLC 4402 as a Guest WLAN controller on the DMZ of our network. I have successfully managed to get our internal controllers to connect to it, with the exception of 1. it says the control path is up but the data path is down. the other 14 controllers worked fine, and in testing the last one was OK but it is now not working properly. the 2 controllers can ping each other but just won't create the data tunnel. there is a firewall in the middle but that has been set up to allow traffic between the 2 groups of controllers to be unrestricted.
 
the internal controllers are 4404's and all controllers are running the same version of code. 5.1.151.0.

Cisco Switching/Routing :: How To Upgrade WS-C6509-E IOS

Oct 14, 2012

We would like to install a WS-SVC-WISM2-1-K9 in each of our 2 WS-C6509-E chassis.  Both of these have supervisor 720 engines installed.  One in each chassis.From what I have read we need to upgrade the IOS to 12.2.33 SXJ4.  Is this correct?If this is true then what are the memory requirements for the upgrade to this IOS version.  Below is the output from Show version?Is there sufficient memory instqalled to do this install?

Cisco :: 5508 / C6509 - Using WLC For DHCP For One SSID?

May 17, 2011

We have a network of multiple WLCs: 5508, 4402, WISMs in two C6509 all running version 7 software. We have about a dozen SSIDs and we need to provide DHCP to the one public SSID (which like the other SSIDs span across all controllers) and to do so we thought of using a spare router, Linux workstation or DHCP server on the controllers. We are not sure if using the controllers is an option since we have multiple controllers. Is there a way to setup DHCP on a WLC and tell the others to use that WLC for DHCP for the one SSID?

Cisco WAN :: C6509 - Error Message In Syslog

Sep 15, 2009

We have 2 Cat 6509 connected to 1 Gbps Ethernet WAN Link. On each 6509 we use 2 Gbps IPSec SPA Encryption cards for Encryption. The encrypted traffic goes to a GRE Tunnel. This morning I found some error messages in syslog.

%CONST_DIAG-SP-3-HM_TEST_FAIL: Module 1 TestIPSecEncrypDecrypPkt consecutive failure count:2
 
There were also several short tunnel downs/ups. I wonder if there is a bug in the new IOS image 12.2(33)SXI2a. We upgraded to this image last weekend.

Cisco Switching/Routing :: C6509 To Have Feedbacks About Vss Availability

Mar 9, 2012

we plan to implement VSS on our datacenters (C6509/Sup720), in order to remove L2 loops (currently, access layer are C3750 stacks, which could evoluate for N5K/N2K). I would like to have some feedbacks about VSS stability. Some years ago, I have seen some bugs with this technology in another company, so I am still not totally comfortable  to use it in the datacenter.

Cisco Switching/Routing :: Impact Of ACL On C6509 CPU Utilization?

Apr 4, 2012

We plan to implement a large number of ACL on our Distribution switch which is a HSRP pair of 6509C switches running on sup-bootflash:s72033-psv-mz.122-18.SXD3.bin WE need to divide the Network in three layers
 
unsecure layer
Proxy layer
Secure layer
 
We have approximately 250 vlans on the our distribution switches and plan to implement 15 ACL on different vlans Each ACL can contain upto 30 lines or less.
 
basic ACL example we will be applying on different vlan
vlan 200
ip access-group test123 in
 
My question is Can these ACL on a vlan can have a massive impact on the 6509 CPU ?

Cisco Switching/Routing :: What Should Be Minimum IOS Version On WS-C6509-E

Sep 26, 2012

what should it be the minimum IOS version that I require on my WS-C6509-E equipments to support "logging origin-id" command?

Cisco documentation says that this command was introduced in 12.2(15)T, and integrated into 12.2(33)SXH.
BUT my Cisco switches have 12.2(33)SXH5 IOS version......and they do not support "logging origin-id".

Cisco Switching/Routing :: WS-C6509-E Doesn't Remove IPs From ARP

Mar 25, 2012

we have a WS-C6509-E WITH SUP VS-S720-10G, and IOS s72033-advipservicesk9_wan-mz.122-33.SXI5.bin. [code]

From, what we can see, whenever we try to clear arp-cache, it doesn't remove the IPs from the ARP. We've checked a bug in the IOS 12.2(33)SXH4 with the same issue, in version SXI4 is solved, but I have version SXI5, it is supposed to be fixed, from this caveat CSCtf16300, since it says it was fixed on 12.2(33)SXI4, it should be fixed on SXI5, right ?

Cisco Switching/Routing :: Monitor ICMP Traffic On C6509?

Dec 22, 2011

Both regular IP traffic and ICMP traffic are passing through the source port. C6509 provides the option of filtering vlan traffic during monitoring. But I don't have vlan traffic.
 
qa-c6509-c(config)#monitor session 1 filter ?  vlan  SPAN filter VLAN
 
So I applied an access-list which only allows icmp traffic to be sent out of the monitoring port. But it does not work.

Cisco Switching/Routing :: C6509 Switch Port Over Subscription

Nov 25, 2012

I have a C6509 with WS-X6548-GE-TX port module. The first port group, 1-8, is showing oversubscription (packets dropping) in the shared buffer. What interface commands can I use to find the specific port causing the buffer overflow?None of the ports is continuously overutilized and none of them in a SPAN destination group.I don't want to move connections without knowing which one is causing the problem. Also I fear that moving the connections may shift the bleeding to another shared port group.

Cisco Switching/Routing :: WS-C6509-E - Possible To Boot IOS From TFTP Server

Oct 21, 2012

I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration

Cisco Switching/Routing :: What Is Heat Dissipation Of C6509-E Configured

Sep 10, 2009

I am trying to figure out what is heat dissipation of a C6509-E configured as follows:
 
1 x WS-C6509-E-FAN
1 x VS-S720-10G-3C
1 x VS-F6K-PFC3C
8 x WS-X6748-GE-TX
8 x WS-F6700-DFC3C
2 x WS-CAC-6000W
 
I have tried two ways: 1) the power calculator and 2) manual calculation using the C6500 installation guide.
 
1) The power calculator says 13630 BTU/h
 2) Manual calculation says: [code]
 
The there should be also the two PS in the picture, and the new total should be: [code] Well, 62711 BTU/h looks quite a bit too much and I think that the heat dissipation of the power supply should't be considered in the calculation.Isn't it an item that takes power from the grid and that generates heat according to its efficiency as the other modules?

Cisco Firewall :: Running 10Gig Traffic Through FWSM On C6509

Oct 30, 2011

Our customer is experimenting really bad performance when running 10Gig traffic through FWSM on C6509. Test with1 Gig traffic are providing find result perfromance as expected in this document: url... I have made a simple drawing so everyone can understand the setup:
 
The issue is when running 10 Gig traffic between Netapp servers. This traffic is going though the FWSM and the perfomance are really bad: around 50 Mbit/sec. If the traffic is not going though the FWSM ther performance are around 900 Mbit/s.
 
The customer and I think that the issue is releated the buffer in the C6509 and the FWSM which has big trouble managing 10G to 1G traffic convertering between C6509 and FWSM 6 G etherchannel connection.
 
When running 10G traffic through FWSM the number of output drops are increasing as you can see on the output bellow. The last thing which is wired a is that the speed is showing 1000 Mbits and not 6000Mbits. [code]

Cisco Switching/Routing :: C6509 - Broadcast Not Working Between Primary And Secondary IP Address

May 11, 2012

I have recently configured secondary ip address on LAN Interface of Cisco C6509.. We have some application which needs to use broadcast traffic communication to communicate with client... Broadcast is working within subnet    & also working from broadcast server to primary subnet. But not working from secondary subnet.. I have checked broadcast within secondary IP range & it's working fine...  Secondary not working broadcast with primary and also with broadcast server... broadcast address is different for these subnet but both should be communicate since configured on same interface... When I went through Cisco website found that command "ip directed broadcast" which will pass broadcast to different subnet... But I'm not sure whether any other impact if I enable that command on particular Ethernet interface...
