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 :: Impact Of Deleting And Creation Of SVI Interface On PBR 6513

Apr 22, 2013

I have a query regarding the deletion and creation of one of my SVI interface on 6513 ,The reason behind it as follows.My traffic get to Internet in this manner
 
proxy(external int.)[IP:192.168.1.30] --> Gi0/9[6513 in VLAN 170] --> SVI VLAN 170[IP:192.168.1.10] --> Gi0/10[In VLAN 170] -->ASR[IP:192.168.1.20],I need to assign this VLAN ie 170 to my inside interface of firewall but it was mentioned in books like this  "Assign the VLAN for the FWSM before it is applied to the MultilayerSwitch Feature Card (MSFC)." so I am thinking the following steps to assign VLAN 170 to firewall group first before creating SVI Interface for it
 
1.Remove all currently assign ie Gi 0/9 & Gi0/10 interfaces from this VLAN and then delete this VLAN.
2.Create the same SVI ie  VLAN 170[IP:192.168.1.10] by this way the issue can be resolved.
 
As in part of my configuration PBR is define like this .
 
interface Vlan170
description "PUBLIC IP VLAN"
ip address 192.168.1.20. 255.255.255.0
ip policy route-map NAT
 route-map NAT permit 10
match ip address 101
set ip next-hop 192.168.1.10
 
I need to clearify what impact it may have on PBR part if I delete and create the VLAN 170.Will the traffic move to the inside interface of FWSM.

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 :: 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 Switching/Routing :: C6509 Loss Of Packets ICMP Sent By Different Hosts In Different VLAN

Oct 17, 2012

I've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
 
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
 
When I send consecutive ping message I  found always a missing of packets . Furthermore When I insert the  "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
 
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.

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...

Cisco Switching/Routing :: 6500 / High Switching Processor Utilization?

I am seeing a strange situation on my 6500 switch?By having snmp walk on '1.3.6.1.4.1.9.9.109.1.1.1.1.3' (== cpmCPUTotal5sec), I came to know that there are two processor and the cpu util for switching processor is gone to 88 % and some time creeps to 99 %.
 
snmpwalk -v2c -c "removes"  sw6500 '1.3.6.1.4.1.9.9.109.1.1.1.1.3'
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.1 = Gauge32: 12 (--- this is for CPU of Router Processor )
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.3 = Gauge32: 99 (--- this is for CPU of Switching Processor )
 
but when I do sh process cpu on the console, all looks normal as it shows cpu utilization of RP.  why the value is so high on the switching processor ?
