Nov 29, 2011
problem to configure MWAM. I have installed MWAM module in 6506-E slot 2 with sup720-3B. After installing MWAM the Status is PwrDown. I tried to turn on the power but its not happening. MWAM is installed in slot 2 and here is the result of show module 2 My Sup720-eB IOS image is s72033-advipservicesk9_wan-mz.122-33.SXJ1.bin

I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video). So this is not a scenario where there is 1 sender and many receivers. This would be many senders (~50) and some receivers (~10)
Sample Diagram:
->3560
|
6506 --> 4506 --> 3548
| |
| --> 2960
|
4506 --> 2960
|
-->3548
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network.
#1 - Is it correct to us sparse-dense mode in this configuration?
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose. Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
#3 - Is there any other configuration settings I should be considering? I hard to find real world configurations of multicast as examples or people that know multicast routing well.

I upgraded the IOS on 6506E, SUP 720-10GE, non-redundant, to a new one, rebooted OK. Switch seems to work fine but "show bootvar" shows the previous IOS name instead of the new one: s72033-advipservicesk9_wan-mz.122-33.SXJ3.bin.Removed the old IOS name on "boot var", gave it new IOS name, "show bootvar" now has correct new IOS name, write mem again and reloaded switch.It booted up OK but "show bootvar" still has the old IOS: "s72033-ipbasek9-mz.122-33.SXI2a.bin".According to IOS upgrade procedure, after all the upgrade IOS steps done, then just "write mem" then the "bootvar: will have the new IOS name, but on my switch it is always has the old IOS name ? How can I set the bootvar to new IOS name?

I have a Cat6506. There were 2 Sup 720 in it for redundancy. They told me they had problems with this thing in the past needing to go out and reboot the machine. I need to go out periodically because it goes into ROMMON. I type boot and it comes back up. One time though neither one would reboot. I had to take a third one out there and reconfigure it. Now it is starting to do the same thing. One thing I did notice is they never connected it to an UPS. It is plugged strait into the wall with power going to two outlets. I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.

Access-group only allows me to set the mode.access-group > mode > prefer > port > int g2/1,Those are the only options available to me, it doesn't allow me to go.ip access-group <name> in or out or access-group <name> in or out.
I realize the commands may be a little off, I don't have a switch nearby. When I get on our 3750 there are no issues, it allows you to apply the ACL the conventional way. I just can't seem to find any way to apply an ACL on an interface on the 6506 though.

I have received a sup720-3B from Cisco with an internal 512MB flash(sup-bootdisk). I want to verify what IOS image is on the disk and do not have an spare 6509 chasis. Can I remove the 512 MB flash disk and insert it to my disk0: on my production 6509 with the sup32 that the 720 will repplace and view what is on the disk without corrupting?

I got a new VS-S720-10G it had 122-33.SXH8b on there. I had to downgrade it to 12.2.33.SXI1 to match our other switches. I installed the file I use in all the other switches, s72033-adventerprisek9_wan-mz.122-33.SXI1.bin but the Sup is now is only booting up only to ROMMON mode.

We purchased two new 4948 with two 10GE uplink ports and upgraded the devices to run IOS 15. My 6506 is running Sup 720 with s77233-adventerprisek0_wan-mz.122-33.SXI9. Currently we have 4948's connected to the same 6506's with no problems. Today I tried to add the new switches with new IOS and it caused of of my 6506 core switches to failover. I can't explain why because it was close to start of business and couldn't do much troubleshooting.
Currently we have four 4948 (running IOS 12.2(14) switches running Layer2 connecting dually to each of the two 6506 cores via 10GE fiber uplinks. I tried to add two more to the scenario, again running layer2 and dual-honing them to each of te 6506 switches. there are two 6506 core switches and they run HSRP and spanning tree is manually set to give priority to even vlans on one 6506 and odds on the other 6506. Also the new switches I tried to add did had rootguard applied as well as the uplinks.
We have to get this working and have no test environment to work with. We need to do this late this evening after close of business.
On another note, I have had problems upgrading some of my older 4948's to IOS 15. I followed Cisco's suggestion and upgraded the EPROM first and then the IOS upgrade took on three of the switches that were ordered rather recently. The four that were ordered in one batch will not take the upgrade even following Cisco's instruction and lots of other tricks. Nothing works. Having problems with IOS 15, in general?

I have a problem with high CPU load by DHCP Snooping process on Catalyst 6506 (WS-SUP720-3B, soft: s72033-ipservices_wan-mz.122-18.SXF11.bin). I have it enabled on 15 VLANS, in which there are subscriber devices residing, and sending DHCP requests through Cisco to DHCP server (Cisco acts as DHCP relay, and it's collecting the snooping database, I also use DAI).
Snooping database contains 6962 bindings now.
CPU load goes high only sometimes, and I don't have a clue, why it's going so high. It can load as high as 45-47% of CPU, like this:
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
116 81471244 322596368 252 42.95% 43.48% 36.06% 0 DHCP Snooping
When the load is high, the command: show ip dhcp snooping statistics is showing, that the overall quantity of
Packets Processed by DHCP Snooping is increasing rapidly. In normal situations, it's like 10-20 packets per second, but when the load is high, it's 1000-10000 pps.
But when I look at SPAN from my subscriber's VLANS, I don't really see any flood of DHCP requests, or something like that - everything looks as usual. Maybe, some of subscriber's devices are sending incorrect DHCP requests, that are causing packets to loop inside RP, or something like that? How can I detect that thing?
Also I thought, that if I enable the ip dhcp snooping trust mode on all of the Catalyst interfaces, the DHCP snooping will not process the subscribers DHCP packets, and I can, by exclusion of interfaces from one to one, detect, from which interface the problem is originating. But this seems to be incorrect, I turned the ip dhcsp snooping trust on all interfaces, and I still get spikes of CPU load by DHCP snooping process. Why it's still examining packets, even on trusted interfaces, is it ok?
And one more question - if I disable the ip dhcp snooping globally, will it clear all my existing bindings in snooping database?

Trying to find documentation on the proper procedure for installing a second sup720 into our 6509-E chassis for sup redundancy. I have found documents that tout how 'cool' and 'awesome' NSF/SSO, and all that is, but haven't found any docs on installing a second sup720 into a chassis that is currently in production and is only running one sup720. In all the years that this chassis has been out, there must me a documented procedure out here to explain this.I have been through the following pages, and have found nothing to this effect.

We are close to receiving our new 6513E chassis which I will be running Sup720 cards in. This will be replacing our existing 6509 Sup2 setup in production. What current IOS version should I run on the Sup720 ? I would like to support SSH. The chassis will be populated with a couple of 6724 SFP cards, 2 6704 10 gig cards and a few 6748 line cards.Is there a good intitial config guide ?

Customer is using SUP720 with SP rommon image version 8.1(3), he is trying to boot the new ios image from disk0, but he gets invalid magic error. he fomat the disk0 but still he gets error when he boots from disk0. He suspect that it can't be flash problem but can be software of hardware as he has two flash with same issue on 2 switches.
Customer wanted to recreate, I tried in the lab, i was able to load from disk0, but sup in lab had 8.5(4).
Customer wanted me try with 8.1(3) version. But i was unable to downgrade the SP Rommon image. SP rommon is running in Gold region and I loaded the 8.1(3) from both disk0 and sup-bootdisk, even preferrence was given to region1 but still sup came up with gold region itself.
* Will i be able to downgrade from 8.5(4) to 8.1(3), if so, what are the steps.
* is there any limitation or bug where 8.1(3) will be unable to read disk0.

I'm trying to boot this IOS on a 6506-E, s72033-adventerprisek9_wan-mz.122-33.SXI8.bin.
This is what I see in bootvar.
sh bootvar
BOOT variable = disk0:s72033-adventerprisek9_wan-mz.122-33.SXI8.bin,1;disk0:s72033-ipservicesk9-mz.122-18.SXF8.bin,1;
CONFIG_FILE variable =
BOOTLDR variable =
Configuration register is 0x2102
Standby not ready to show bootvar, I want to remove SXF8 and leave SXI8 alone. I removed both IOS file names in boot system and added the SXI8 again and saved. So this would be the output after.
But after a switch restart, this would be the output of show bootvar again.
sh bootvar
BOOT variable = disk0:s72033-adventerprisek9_wan-mz.122-33.SXI8.bin,1;disk0:s72033-ipservicesk9-mz.122-18.SXF8.bin,1;
CONFIG_FILE variable =
BOOTLDR variable =
Configuration register is 0x2102
Is there anything I need to check? This is an old engine and I'm not sure if the variables of the RP modified .

I have a 6506-E with 720 Sup. I am trying to connect a server with HP 550SFP Nic to my 6506.If I plug the SFP from my server into my 6506 it will not link. When I plug that very same SFP into a 3750 it links fine. Makes me think that there is something I am doing worng on the 6506 Config.But, If I plug another server using a IBM LAN Card into the same port on my 6506 it connects and works fine so now I am starting to wonder.

We currently have an existing 6506 in data center that we want to add another 6506 to and do a VSS implementation.I'm trying to minimize down time so our current basic plan was to do the following:
1. Bring up the new 6506 and configure it for VSS
2. Trunk a port between the new 6506 and the production 6506
3. Physicall move connections from the production 6506 to the newly connected VSS switch
4. After all physical ports have been moved, power off the original 6506 swap the supvisor card out for the new 2T Sup card
5. Configure original 6506 for the virtual domain and then connect the VSL's.
According to the documentation, to run "switch convert mode virtual" the standby unit has to be in hot standby. This means I can't run this prior to moving the connections over, which means once I run "switch convert mode virtual" it will reboot the switches (~ 9 minutes of down time). Is there anyway around this?

I am having problems with IGMP and QoS on CAT6500 platform with SUP720 engine.The problem is, it seems that all IGMP packets are getting marked with DSCP 48 when sent out of the switch regardless of any input service policy. I found several articles saying that PFC QoS does not apply to IGMP packets. However in IOS 15 that should be possible, but I didn't get it to work there either. [code]

Supervisor Engine 720 options support centralized forwarding rates up to 30Mbps and distributed forwarding rates up to 400Mpps. I never understood the claim of forwarding rate logic in mbps. How i can load the 6509 box to check this forwarding rate?How can the performance increase from 30mbps to 400mbps? is this just because of DFC on all the line cards if yes does it mean i have to add the DFC on SUP as well .
