I am migrating services from SUP720-3B to VS-SUP2T-10G= and moving to a VSS configuration between a pair of Cat6506 distribution layer switches. I need to enable QoS on these switches, primarily to trust dscp and also to prioritise voice traffic. The autoqos feature works for some ports but does not work on port-channel interfaces and port-channel member interfaces. How can I apply the qos settings for these interfaces in line with what auto qos would normally provide. My line cards are as follows:
Civic_6506VSS#sho mod
Mod Ports Card Type Model Serial No.

Cisco 6500 with 2T supervisor engine with following software Cisco IOS Software, s2t54 Software (s2t54-IPSERVICESK9-M), Version 15.0(1)SY1, RELEASE SOFTWARE (fc4)
The problem is that, I am not able to configure Multilayer Switching (MLS) (mls rp ip) in the global config command. Although the "mls" is visible on the config menu. but when I say "mls ?", the router prompt "unrecognize command"
Not sure if SUP 2T support MLS or it come with different name.
I got problem with wake on LAN software.. The software unable to ON all pc's remotely if sitting under different vlan. Everything is ok if using the same vlan. Below are the network diagram & switch configuration.
Layer 3 switch Intervlan routing configuration
ip forward-protocol udp 7 ! interface Vlan4 description vlan Client-WOL ip address 172.22.51.253 255.255.254.0 ip access-group Deny_HTTP_Vlan1 in ip helper-address 172.20.1.246
[code].....
After configured all the switches with the above setting, the software still cannot wake all the pc's using LAN. Base on sniffing, i can't find UDP port usage by the software. Attached here with print screen from wireshark.
I am trying to upgrade Sup2T from 15.0 to 15.1 (same feature sets). I have the new image in bootflash and have changed the boot system statement to boot from the new image and the config register is 0x2102. However, everytime it reboots it loads the old image. [code]
We recently purchased 2 Cisco 6500 series switches (with Sup 2T). These switches will be replacing our old 2 6500 series switches (with Sup 720).
We have 70 vlans and 90+ closet switches (2900) connecting the core switches We have 2 WLC connected to the core switch. We also have a 1 x 1 connection to a VSS switch which in turn connects to our Server Co-Location data center utilizing IPSec & GRE tunnel to connect to our Server Co-Location data center.
Our routing protocol is EIGRP. Our VTP domain at Server Co-Location is separate from our location “A” campus. I was wondering what is the best way to migrate our Core switches at location “A” campus.
The requirement is we would like to replace these switches with minimum downtime.
document which explians normal booting sequence in a 6500 Switch running IOS. What I am looking for is in which order the image is loaded in SUP, RP, SP etc
1. We now have SupA & SupB in the chassis, due to some mistake we have same IOS version but different feature set on them, although we configured redundancy mode sso, in the "show redundancy" we see Operating Redundancy Mode = rpr due to Software mismat, we now need to fix them as same feature set image, if I use "copy sup-bootdisk0:/xxxx slavesup-bootdisk0:/xxx", then write memory, does this cause any service/network interuption?
Available system uptime = 1 year, 1 week, 4 days, 9 hours, 21 minutes Switchovers system experienced = 2 Standby failures = 0 Last switchover reason = active unit removed
[code]....
2. We did a failover test with this status, found that if we triggered supervisor failover, all modules will reload thus the services if interupped. How about after we make the Operating Redundancy Mode as sso, will this behaviour shows again? Or a stateful failover will happens, then modules no need reload?
3. We are using OSPF as our L3 routing protocol, after reference to the configuration, nsf should be enabled, we want to ask in the OSPF-domain nsf should be configured in all OSPF-enabled router or only 6500 which have dual-sup?
4. We also found that the interfaces(3 * Gig & 2 * TenG) in Standby supervisor cannot be use even enabled & configured, is it because we are running rpr mode now or will be the same even change to sso? Before customer have some older supervisor in 6500 non-e chassis, and they can use the standby supervisor interfaces as traffic forwarding, they use rpr-plus mode before, how about in sso mode?
"How to display the EOBC error counters in the Catalyst 6500 series switches and a definition of the EOBC interface" document here on support forum stays that The Ethernet Out of Band Channel (EOBC) is a half duplex channel that services many functions, which include the Simple Network Management Protocol (SNMP) and the packets that are destined for the switch.
Previously i were thinking that EoBC used only for SCP and SLP protocol. In addition i found other article (but not on cisco site, heh) where stays that The Results bus is a control plane, while the C (EoBC) bus is more of an "admin plane", thus you will never see data packets (such as CDP, SNMP, etc.) going over the R or C bus.
So there is a big contradiction between those two statements. How to prove one of those and if first one right, what meaned under the packets that are destined for the switch in it? SCP and SLP or other traffic as well?
The diagram below is the configuration we are looking to deploy, that way because we do not have VSS on the 6500 switches so we can not create only one Etherchannel to the 6500s.Our blades inserted on the UCS chassis have INTEL dual port cards, so they do not support full failover.
Questions I have are.
- Is this my best deployment choice? - vPC highly depend on the management interface on the Nexus 5000 for the keep alive peer monitoring, so what is going to happen if the vPC brakes due to: - one of the 6500 goes down - STP? - What is going to happend with the Etherchannels on the remaining 6500? - the Management interface goes down for any other reason - which one is going to be the primary NEXUS?
Below is the list of devices involved and the configuration for the Nexus 5000 and 65000.
Devices
· 2 Cisco Catalyst with two WS-SUP720-3B each (no VSS) · 2 Cisco Nexus 5010 · 2 Cisco UCS 6120xp · 2 UCS Chassis - 4 Cisco B200-M1 blades (2 each chassis) - Dual 10Gb Intel card (1 per blade)

Is it possible to issue eigrp leaking routes on catalyst 6500 running IOS 12.2-33SXI9 on gigabitethernet interfaces? or is there another way to acomplish this?
and i see output "show interface Po4A" up up on switch-1, "show interface Po4B" up up on switch-2
5.- In the show running-config not appear configured Po4A and Po4B. it only show on outputs
6.- Po4A and Po4 was not configured on neither switches, my question is why appear Po4A and Po4B on switch-1 and switch-2 respectively? and why Po4 appear in down down.
7.- I solved this issue by shutdown and not shutdown to the interfaces on both routers, currently all is OK.
I understand that my questions seems to be rather strange cos supervisors is rather old (Sup1A especially). But i am interested in understanding what puprpose were in production SUP32. I cant find out enough differencies between Sup1A with MSFC2 and Sup32 to understand what reasons lead to deploying new sup in none fabric supervisor series.
Both supervisors have same perfomance - 15Mpps and have limitation on backplane bandwith of 32 Gbps (cos both use swithing bus), both supervisors equipped with MSFC2 and etc. Differencies i found:
SUP 32 have 10Gbe ports support (but this seems to be doubtful enhancement - with it perfomance GE ports seems to be more appropriate technology isnt it?) SUP1A equipped with PFC, SUP32 with PFC3BSUP32 deploys CEF (what is benefit of CEF if perfomance same?)
On a Catalyst 6500, we configured a SPAN session with VLAN 300 as a source. We configured the session bi-directional ("both" keyword). We connect a sniffer on the SPAN destination port.
Strangely enough, we only see the traffic from the VRF to the firewall, but not the reverse traffic ! What can be the problem ?
Are there any best practices for preventative maintenance on Catalyst Chassis switches. Looking to build a PMI schedule for a customer. Or is there evidence not to perform it at all. Things like re-seating line cards, cleaning fan exhausts, etc.
I'm trying to get ERSPAN working with an ERSPAN source on a Nexus 5548 and the ERSPAN destination on a Catalyst 6500.
The configuration on the Nexus is as follows:
[...] interface loopback0 ip address 192.168.2.133/32
[Code].....
If I do a netdr capture I can see ERSPAN traffic sourced from the Nexus reaching the C6500, but there doesn't appear to be anything sent out the ERSPAN destination inerface (Gi4/6) and there's nothing being received by the probe connected to that interface. I know the traffic seen with netdr is definitely the ERSPAN traffic sourced from the Nexus as I've changed the TTL and DSCP values within the monitor session on the Nexus and can see those changes reflected on the C6500 netdr capture. The attached is a screen grab of the show netdr capture started with debug netdr capture soure-ip-address 192.168.2.133.
When I look at the interface I see it shown as up/down (monitoring), but no output or counters clocking up. If I run a local SPAN session on the C6500 it works fine.
I've tried changing the destination IP address from that assigned to the C6500 Loopback interface to an IP address assigned to a physical interface, but that still doens't work.
The hardware in the C6500 is WS-SUP720-BASE Hw version 3.2 with WS-F6K-PFC3B Hw version 2.4. The IOS version is 12.2(33)SXI6.
I came across this Multichassis EtherChannel Features when read about information from Cisco Smart Business Architecture.After checking further, knowing that Cataly stwitch 6500 supports this feature.provide information that beside Catalyst 6500, is there any other model of Catalyst switch can support this feature?
I manage a small/medium sized campus network consisting of 4 Cisco 6500 series chassis (each with SUP720's) and a couple hundred Cisco 3550/3560/2960 edge switches. We recently completed a new leg of fiber that will make a completed loop between all of the 6500's .... before I make the pyhsical connection I need to figure out my OSPF entries on each 6500 switch.
I am going to change a running 6500 switch. I am missing a best pratice doc for changing a cisco switch configuration. My question is if a startup-config has an error (due to typo mistake, or due to comands not supported on latest IOS) and I do copy tftp startup-config then what will happen ? I want to make sure when I do "reload" the switch then it should boot normally with the latest startup config !
First time I have create SVI interface on C6500 and enable trunk on interface that connected to SW2960 and SW2960 assigned access vlan 100 on port connected to Notebook. Then I tried to ping from Notebook to C6500 on SVI100 which work fine.
Second time I tried to enable MST on C6500 and after that everything still working and I can ping from Notebook to SVI100 on C6500.
Third time I tried on turn on dot1ad in global configuration mode and from now I can't ping from Notebook to C6500.
Forth time I tried to disable dot1ad from global configuration by "no dot1ad" command and then I can ping.
My intention is I would like to do EVC which require dot1ad in global configuration but I stuck in third step and don't know what's does it mean for this command and how I can resolve this issue?

I have got a catalyst cisco 2960G series switch and via this switch I want to creat serveral vlans. I am getting a dhcp IP from a router and I want to setup my own vlan networks.
I plugged in the Ethernet cable that came from the dhcp router to port 16 of the cisco switch and configured the ports 1,2 and 3 for vlan 1, 2 and 3
the dhcp router has given me this IP 192.168.10.158 defautl gateway is : 192.168.10.1
when I plug in a PC to port 1 or 2 of the cisco switch I still receiving the IP from range 192.168.10.* but not from the range that I configured for the vlan 1 or 2.
Below is my startup configuration:
no file verify auto spanning-tree mode pvst spanning-tree extend system-id
