Cisco WAN :: 6506 - How To Configure RTR In Network
Jun 4, 2012
We want to configure RTR in our network ,having a Cisco 6506 core Switch & 50 Cisco 2960 Switches. As per the ios on the 6506 the rtr command is supported not the ip sla , so we want to configure it on it.
The RTR configuration on the Source device (Cisco 6506 Sw) can be done through the below commands :
1) enable
2) configure terminal
3) rtr <Entry number>
4) type echo protocol ipIcmpEcho <Hostname or A.B.C.D IP address or hostname> source-ipaddr < IP address >
5) frequency seconds
6) exit
7) rtr schedule entry-number [life {forever | seconds}] [start-time {hh:mm[:ss] [month day | day month] | pending | now | afterhh:mm:ss] [ageout seconds] [recurring]
8) exit
RTR configuration on the target devices (Cisco 2950 SW )will be :
2) And for every Cisco 2950 Switch , i have to create seprate rtr entry on Cisco 6506 Sw for example for 50 target device i have to create 50 entries on source device 6506?
Multicasting. The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10. I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch. On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10. The 2960G switch has a workstation connected to it that needs to receive the multicasts. How do I configure the 6506 and/or the 2960G to process the multicast traffic?
I'm trying to configure my BRI interface in "network protocol-emulate network" and "layer1-emulate network" but i don't have this second command.Is someone have allready to that with this type of interface ?I've to configure this because the ISDN line of my telco is in user mode only.
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 scenario with a Cisco 6506 and a 7206. The 6506 is running BGP and peers with our data center router. The 7206 is a stub router off the 6506 and is used as an edge router for customer T1 circuits. I want to use OSPF between the routers to exchange connected and static routes. The problem I have is that static BGP null routes on the 6506 are overriding the OSPF routes being received from the 7206. Example: The 6506 is advertising a class C network 192.168.1.0/24 to our data center. The 6506 does not utilize the 192.168.1.0/24 network. It is only used on the 7206 for customer T1 circuits and is carved up into /29 subnets. So the 6506 has a static route: ip route 192.168.1.0 255.255.255.0 null 0. Today the routing is accomplished with static routes on the 6506 for the 192.168.1.0 networks on the 7206. Using OSPF the 7206 advertises /29 links back to the 6506, but when I withdraw one of the /29 static routes from the 6506, the /24 null route takes precedence over the more specific /29 routes and the traffic is black-holed on the 6506. how can I get the OSPF routes to look preferable to the /24 null route on the 6506?
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.
I want to receive full BGP in my switch 6506 with the follow characteristics: cisco WS-C6506-E (R7000) processor (revision 1.2) with 458720K/65536K bytes of memory and Supervisor Engine 720.When I configure the session BGP in my router with me peer the switch begins to work slow and restarts.
I'm replacing a PA-POS-OC3-SM with PA-POS-1OC3 in a flex Wan module (WS-X6582-2PA) in Cisco 6506 using WS-SUP32P-GE PISA.I have a hard time bringing the "protocol up. the status I see is line up and protocol down. Debug shows (attached) no comunication with the edge router but when i put the older PA (PA-POS-OC3-SM ) back evertything works fine and older PA has been running for many years without the issue. I'm replacing older PA is becuase this is going EOL. I had opened a TAC case but the TAC engineer added no value. [code]
I am little confused of how to take bootloader backup of cisco 6506 switch with WS-C6506-1300A CHASSIS and WS-X6K-SUP2-GE sup I am pesting a the part of sh run to show you the image files for the switch.
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 tried to upgrade IOS from SXI2a to SXI9 in cat 6506 VSS. But the problem is that switch always boot with old IOS. I put the new IOS in sup-bootdisk and slave sup-bootdisk, bootvar is ok with new IOS: [code] Show bootvar is ok but switch always boot with old IOS SXI2a, some bug in IOS sxi2a???, I will try to delete de old IOS from sup bootdisk and try with the new one only.
I have PAT set up successfully on 6506 chassis - My outside address range is 78.24.112.114 255.255.255.240.Relevant parts of the config below: [code] This works fine but of course is only using the one IP address 78.24.112.114.how I can utilize the other outside addresses available or is this not really necessary? I've browsed through loads of Cisco docs.
I currently have a vlan/SVI on my 6506 for the WiSM service-port. The WiSM has an address on the same subnet. To manage the WiSM, I either https to the Management interface address or use 'session slot X proc Y' from the the 6506. Since I am essentially only using two addresses from a subnet for this service-port I would like to free up the subnet. Can I keep my current functionality by having a vlan only (with the wism service-vlan XX command) with no SVI?
The core switch is a 6506 and one of the modules is the 48port POE module. The 6506 resides in the main building and we need to interconnect two other annexes to the main building via fibre. is it possible to have just 2 sfp ports on the 48 port module or how to connect the fibre cable to the switch?
Also, if the existent network is made up of Cat5e cables would it be of anyuse to use Cat6 cables for uplink for the switches on each segment to the core switch. I feel basically the Cat5e would nullify the speed of the Cat6 or am i wrong and this would make uplink speed faster.
We have one Catalyst 6506 ( with WS-SUP720-3B, IOS is 12.2(18)SXF14 ) and one Catalyst 6509 ( with WS-SUP720-3B, IOS is 12.2(18)SXF17a ). We used WhatsUP to collect I/O & process memory utilization for both switches. The memory utilization for Catalyst 6509 was ok, but it seems not correct for Catalyst 6506 ( show proc memory displayed the total memory is 512MB, but the WhatsUP displayed only 64MB only )
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:
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?
We have a three tier network with a centralized core switch and multitple distirbution swithces - all 6506 routers.EAch dist switch is its own PIM SM domain and the RP so we never send multicast between the dist switches and through the core.
We are putting in a centralized server at the core switch which has to provide specific mcast < X Groups > to all servers at the dist level on all dist switches.
So we would like to define the RP <core rp ip> just for the <X groups> on the Core switch and tell all the distribution switch that the core is the RP for just the <XGroups>
If we put these commands on all the switches including the cores will that set the rp just fo the <XGroups> to the <core rp ip > ?Do I have to define the deine an ACL for all groups if i define it for some or will groups not defined by the ACL defualt to the local RP?
do I have to put in the override command ? (We are using MSDP not autorp)
ip pim rp-address <distn rp ip> ip pim rp-address <core rp ip> 99
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?
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.

I've been configured my device 6506-9 with TACACS+ server authentication: [code]
but when I tried to access the device only uses authentication local but not uses TACACs (with username/password defined) it can be an error in configuration? in the other devices of network this works properly, only it's wrong in Cat6506-E
I had these error messages on both my Cisco 2851 and on my Cisco Catalyst 6506.
On Cisco 2851: %SYS-SP-3-CPUHOG: Task is running for (2000)msecs, more than (2000)msecs (4/4),process = SEA write CF process. [code]...
And on 6506: Dec 27 15:20:55 MET: %SYS-SP-3-CPUHOG: Task is running for (2000)msecs, more than (2000)msecs (129/129),process = SEA write CF process.[ code]...

i want to know if 1port of the 16 10Gbase-t Module (WS-X6716-10T-3C) for the Catalyst 6500E Series, can be connected to a 1Gbase Port of a 2900 ISR Routers, are they gonig to work at 1Gbps or, simply, they are not compatible?
If it is true, can i create a 4ports etherchannel between them? of course using the 16 1Gbase-T switch module on the Router.
