Cisco Switching/Routing :: 6500 - Cannot See Which Protocol Is In Use For Etherchannel

Jan 31, 2013

I am trying to review the port-channel configuration on a 6500 series. I am issuing the "show etherchannel summary" command and the out put shows the Group, Port-Channel, and Ports. It does not show me the protocol that is in use such as PAgP or LACP. Does this have to do with the Etherchannel in the "On" mode rather than "active", or "Auto"?

Cisco :: 6500 - MIBS To Monitor EtherChannel And Trunks Via SNMP

Feb 19, 2009

I would like to monitor the status of ether channel and trunk configurations in 6500 Catalyst switches running both CATOS and IOS.  I would like to understand the specific mibs /OIDS that should be monitored for ether channels and trunks.  I am trying to get a better handle on tracking the ether channels and trunk dynamically and then understanding when the ports are having issues (up/down and errors).  I need to understand how to differentiate these type of ports from regular access ports.

Cisco Switching/Routing :: Etherchannel - Redundant 6500 To 3750 Datacenter Switch?

Mar 27, 2012

I have 2 6504's running HSRP as my core.  They are each etherchannel'd to my Datacenter switch (3750 Stack) -- see image below.The problem i a having is with the etherchannel status:

Core1 PO11 status w (waiting)
Core2 PO11 status P(bundled)

DC11 PO48 status P -- but only to Core2 - the interfaces to Core1 are suspended. (See attached configuration documents)  None of the devices have any information in the logs.  I run this same configuration in my central location, but we are running Nexus 7000's.  With the 6500's, do I need to split the port channels on the 3750 to allow them to negotiate the etherchannel? If I split the portchannels, are there any concerns? Should I expect to see the etherchannel status as P (Bundled) or H (Hot-Standby)?

Cisco Switching/Routing :: Etherchannel Suspended Between Catalyst 4948 And VSS 6506E

Dec 23, 2012

I describe an issue when i need to performe an L2 or L3 Etherchannel from a Catalyst 4948 IOS Enterprise and 2 xCatalyst 6506E bandled with VSS.
 
From the VSS Side when i plug cables i see on the physicals and Etherchannel that Physical and protocole layer are up. On the 4948 side, I see that physical layer is up and protocol and Etherchannel interfaces are down.
 
On the Etherchannel port summary i see that the port state is supended.
 
On the first attempt, i have test with a L3 etherchannel on both side using no switchport with two IP addresses one at each side on etherchannel interfaces.
 
The etherchannel are bundled with LACP mode active and on the second attempt with PAGP mode ON. 
 
The same configured on VSS 6506E work fine with Catalyst 3560E.

Cisco Switching/Routing :: Catalyst 3560 Vlan Trunks Over Etherchannel

Jun 20, 2012

I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch.  I need to trunk multiple vlans over each channel group.
 
I created the vlan trunks and allowed vlans on each physical interface.  I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces?  Relevant config is below:
 
interface Port-channel1
!
interface Port-channel2

Cisco WAN :: IOS In Catalyst 6500 Is Not Loading?

May 4, 2011

Two days ago, a brilliant guy inserted a different ios in a Cisco Catalyst 6500 and erased the original ios. I have twice downloaded the original ios by xmodem (too much time!) and both of them, when I reload the 6500, it doesn't work: I have the following message:

loadprog: bad file magic number: 0x0 boot:cannot load "bootdisk:s72033-ipservicesk9_wan-mz.122-18.SXF11.bin"

Second time, when the ios uploaded, I checked the sup-bootdisk: and the flashboot: and both have the wrong ios listed, but it wasn't there: I've tried to delete it and squeeze it, but had a message saying "can't delete because the ios is not there" or something like this. I finished formatting both (flashboot: and sup-bootdisk:), tftp the ios, double-checked the bootloader, compared with other identical 6500 and reloaded again, just to find the same message I've written before.
 
Supervisor 720 PFC3B. Slots for disk0 and disk1 are broken or I can't read them from the rommon.

Cisco WAN :: Egress Queuing On Catalyst 6500

Mar 16, 2012

i have a question regarding egress queuing on cat6500 modules. e.g. WS-X 6704 has 1p7q4t is egress-modell. my goal is to limit the priority queue to 15% of the available bandwidth. i can put weights on the wrr-queues and limit their ressources: "wrr-queue bandwidth 50 20 15 0 0 0 0." but this isn´t possible for the priority-queue. only available command is "priority-queue queue-limit 15" but this only restricts the buffer to 15%.
 
at the end of the day i want to prevent that the wrr-queues don´t have remaining bandwidth when the priority-queue is saturated.
 
is there an easy way to restrict the bandwidth of the priority queue or do i have to implement additionally some kind of policing?

Cisco WAN :: Slow BGP Convergence With Catalyst 6500 Quad

Nov 28, 2012

I set up Catalyst6500 Quad-SUP VSS system.I have a problem with slow BGP convergence(80sec) on VSS switchover.Each chassis has a bgp peer and "bgp graceful-restart" is disabled.I investigated BGP behavior with "debug ip bgp events" and "debug ip bgp update".I found that BGP process waited a peer to reply until timeout and after the timeout BGP table was calculated.I guess this timer makes the convergence slow.How can I adjust this timer value ?

Cisco Application :: ACE SM Indexing In A Catalyst 6500 VSS Environment

Mar 7, 2013

I was asked to mount ACESMs on each of the CAT6K switches of a VSS cluster (one ACESM on each individual switch).On a non-VSS environment, the "svclc module <slot> vlan-group <group>" command is used to bind the VLAN group to the module on a certain slot. But now I am facing a VSS scenario, I will need to combine switch and slot in order to reference each of the individual modules...
 
How do I "index" each of the ACESMs in a VSS cluster? ¿Is there an extension of the aforementioned command to be able to combine switch and slot information?

Cisco WAN :: Used DDR Memory On DFC On Linecards For 7600 / Catalyst 6500

Dec 12, 2011

What is used DDR memory on DFC on linecards for Cisco 7600 or Catalyst6500? I thought that DFC has copy of TCAMs from PFC. That PFC only has TCAMs, and it doesn't have DRAM on itself?
 
I've been said that if I have full BGP table in memory on supervisor on 6500 (that should be DRAM on RP on MSFC) that I also need 1GB additional memory on DFC on linecards? Is this true? But that should implied that DFC also has copy from MSFC not only from PFC, is this correct?

Cisco Switching/Routing :: Catalyst 6500 Dual-Supervisor 720-10G-3C?

Sep 21, 2012

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?

Cisco Switching/Routing :: Catalyst 6500 BUS EoBC Channel

May 5, 2013

"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?

Cisco Switching/Routing :: Catalyst 6500 VS-SUP2T-10G QoS Configuration

Apr 22, 2013

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 WAN :: Route-map Mismatching On Catalyst 6500 Vlan Interface

Apr 22, 2012

we have applied route-map on vlan interface in the form:
 
ip access-list extended TEST
permit ip 172.16.1.128 0.0.0.127 172.16.0.0 0.0.255.255
route-map TEST permit 10
match ip address TEST
set ip next-hop 172.16.111.1
interface Vlan11
ip policy route-map TEST
 
The problem is in the traffic matching by the rule - there is matches not only for 172.16.0.0/16 prefixes but for the whole traffic in that VLAN.

Cisco Switching/Routing :: VPC On Nexus 5000 With Catalyst 6500 (no VSS)?

Jan 23, 2011

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)

I wanna see only the traffic that goes to and come from the wan. On other Catalyst where I have routed interfaces i successfully configured netflow. I read a lot in the forums and documentations but i didn't find the right one.
