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...
We an 887m router in our office with an unmanaged switch. We have two networks, 192.168.0.x and 192.168.11.x connected to router on the same interface (192.168.11.253 is a secondary ip) but I can seem to be able to route packets from one network to the other. Internet traffic is fine from both networks. I can't see what I'm doing wrong here. I can ping the 192.168.11.253 (router) from the 192.168.0 network but nothing beyond that.
I tried this at home with no other config and its the same. Is this by design?
we have cisco WS-C6509-V-E with IOS version 12.2(33)SXI4; s3223_rp_IPSERVICESK9_WAN_M) running on a switch. I am trying to configure the command "mac-address-table synchronize" under global config mode. But when I enter the command Cisco(config)#mac-address-table ?It doesn't show the synchronize option?
I have a few old 2600 routers (2621, different IOS's) which I'm now replacing for new one's from the 2900 series (2901, Version 15.1(4)M4).In my configuration I have two IP addresses in my LAN interface and I have HSRP configured within the secondary IP subnet range. It would be something like this:
interface GigabitEthernet0/1 ip address 172.x.x.x x.x.x.x secondary ip address 10.z.z.z z.z.z.z
[Code].....
Now, in the new 2900 routers, my interface configuration hasn't changed however I can see that the hello packets are now sent with the source within the respective HSRP IP subnet so I had to edit my acl for that:
I have just updated a VLAN interface on my router. I have two 6500's with GLBP configured. The particular interface had a primary and secondary IP address. I shutdown the interface on one router and deleted the secondary address then assigned the orignal secondary address to be the be the only address associated with the interface and enabled the interface and it came right back up...all looks good. I proceeded to do the same thing to the other router and once again all looked good. Now, I am able to PING the devices in the subnet from router, but am unable to ping them from any place else.

How can you figure out your primary and secondary DNS? I have a linksys router, and i'm trying to figure out what my primary and secondary DNS are so i can hook up my PS3 online.
I have been having problems when trying to host servers on games, etc.I have 2 routers. A modem router, which is a Thomson router. That is the main one. It has a wire connecting from it, to a D-Link router that is near my Computer, and my brother's one. Then that D-Link router has 2 wires from each port, to mine, and my brother's computer.So, I am trying to host games.I didn't connect to the Thomson one, which is also wireless. I am connected to the wired one (D-Link). When I try to host while connected to it, my brother, and other people can't find the server. My brother and me can find it on LAN, but not Internet.But when I disconnect from the Wired, and connect to the Thomson wireless one, and then when I host, I can find it on INTERNET. Even my brother can. He can connect to it perfectly.
I do not want to connect to the wireless, because then it will cause lag spikes every 5 minutes.So, when I disconnect from the wireless, and connect to the wire, I went into the CMD, and typed in ipconfig. I found out that the Default Gteway is the D-Link IP.When I connect to the wireless, and disconnect the wired, I went into CMD, and then the Default Gateway is the Thomson one, which is the main router.So what I want to do, is use the D-Link router, and that router will have the same IP as my thomson one, so that I can host perfectly with no lag spikes, and using a wired connection.
I have a question about the number of Cisco licenses needed in two cases for ACS 5.3 Virtual Machine.One primary + One secondary : Just one license for all or one license for the primary + another one for the secondary ?One primary + several secondaries : Just one license for all or one license for the primary + just one license for all the secondaries ?
Today I ran a failover test between our primary and secondary ACS systems (ran 'acs stop' on the primary) and in the process decided to promote the secondary while I had the primary down. All was fine until I brought the primary back up and tried to re-register the secondary to it. I get the following error message: I went into System Administration >Operations >Distributed System Management on each and it showed the other device as deregestered, tried to promote from there but it failed too, so I deleted them and tried to register the secondary again. After that didn't work I tried rebooting both but that didn't work either. I know the user/pass I'm using is good and I've tried using both the IP address and the hostname.

We are trying to configure vrf aware GET VPN with COOP having primary and secondary key servers and also 3 GM routers. All GM routers we use are Cisco 888 and Key servers we use cisco 2911 routers. All GMs crypto maps have been applied into Vlan interface as there's no L3 interface on 888 routers.
Always members can form a tunnel with primary KS, we have configured redundancy with secondary key server and listed on each GM primary and secondary KS on GDOI group.
The issue we facing is that whenever we shutdown the primary or secondary servers the tunnel is not forming with available KS unless otherwise we mannually clear the crypto session. In another way when primary KS down it doest not fall back to secondary KS and no GM get registered. We have already played with all the timers such as DPD, SA lifetimes, GDOI rekey lifetime etc and also exchanging the keys (import/export) with KS and COOPs but there's no luck. We could see the following message was seen on both KS.
[code] 192.168.1.3 is the primary KS and 192.168.1.6 is the secondary KS.I captured attached debug output from 1 GM and secondary KS while I shutdonw the primary KS and also attached is our senario we were trying get work.
Also attached is the show output from both KSs when it form a tunnel with GM.
I have more than 5000 sq. ft home and have some dead places other end of the house. Now I am looking for Range Extender/Repeater to boost signal. My primary wireless router is Motorola Surfboard SBG6580 and Secondary Linksys E3000 (planning to update firmware to DD-WRT). So I wanted something such that I can roam between the two routers without switching SSID (use single SSID name for primary and secondary DD-WRT routers) and connect automatically to whichever the best signal (or) strength router. In work place we have same thing like that single wireless SSID name which automatically connect wireless SSID from one end to another end of the building.
We have 2 ASA 5505s in a data center at a remote site.
Whilst troubleshooting another issue I noticed the below. I don't know much about fail over but this would suggest that the secondary ASA is active and the primary ASA is on standby.
if the primary is "active" then how come the secondary is the active ASA? I would have thought that once the primary ASA became active this would assume the "main" role".
Management purchased a HA package from Cisco consisting of 2 5508's with pre installed 500 users license on the Primary WLC and none on the secondary WLC. We have 5508's already so I am familiar with setting them up and so forth. What I am not familiar with is setting them up using HA for failover and license sharing. I've looked and looked and can't find documentation online showing how to set this up. I have found some but nothing that is complete. I have spent 2 days spinning my wheels.
I have a couple of ACS 5.2 configured as active and backup and I am doing dot 1x authentication using these servers . I have configured the switch with the bellow configuration.
IP address of Primary had to be changed, to respond to a hardware failure of TACACS server with IP in many device configs.
Now the Secondary fails to respond to repeated "Deregister from Primary" requests, even after reload - apparently because it cannot reach the Primary at its old IP address.
Requesting Deregister in GUI generates pop-up that says, "This operation will deregister this ACS Instance from the Primary Instance. Management applications on this ACS instance will be restarted and you will be required to login again. After performing this operation
Cisco ACS 5.2 secondary server is configured as a log collector for both primary and secondary server .Now i am facing problem in log collection from primary server .ACS secondary server is not collecting any logs from primary .
I have a pair of ASA5520s in active/active failover - this works fine. Both primary and secondary ASAs are running 8.2(2) code.I have a 30-day temp 50 seat SSL license that I applied to the primary. I then started having problems with L2L tunnels.
I noted that if the 'show crypto isakmp sa' state for an L2L was MM_STANDBY, then the remote protected net could not reach my side. However, I could ping across to the other side at which time the state changed to MM_ACTIVE as I would expect and the remote could then reach my side.
I believe this results from the differences between the two licenses. When I applied the 50 seat SSL lic. it disabled failover, but I was willing to risk that for a few days to do show my customer the benifits of SSL connectivity. Note license differences. Is this causing the MM_STANDBY IKE issue and if so can I overcome it and use the 50 SSL VPN Peers lic.
How can know the Broadcast address before subnetting? I know how to calculate the broadcast address , but don't understand 'Broadcast address before subnetting'?
Cisco ASA 5505 Security Plus 1 link with PPOE dialup for internet access
desirable situation: Primary link with a PPOE dialup Secondary Link with DHCP address Asignment
Problem: i want to configure Dual ISP Failover modus, but the problem exist when i configure the ip sla syntax it looks good in the running config. but after a reload the secondary line becomes primary
It looks like the ppoe client authentication is busy when the ip sla tracking mechanism becomes active. can i tweak the settings that the ip sla tracking mechanism starts later?
What i the correct config for Dual ISP setup with primary PPOE and secondary DHCP
We would like to install a WS-SVC-WISM2-1-K9 in each of our 2 WS-C6509-E chassis. Both of these have supervisor 720 engines installed. One in each chassis.From what I have read we need to upgrade the IOS to 12.2.33 SXJ4. Is this correct?If this is true then what are the memory requirements for the upgrade to this IOS version. Below is the output from Show version?Is there sufficient memory instqalled to do this install?
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.
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 ?
I have a 2 cisco core (cisco WS-C6509-E (R7000) processor) and been working for quite sometime.they are conneted with HSRP with active standby config with a 10 g module for redundancy just today I see that the cpu utilization went to about 50% and its the same on both cores.
Last night, the C6509-E do a unexpected reload. In the crashinfo, I can see that the last error message before the reload, was as follows: %C6K_ PLATFORM-SP-2-PEER_RESET: SP is being reset by the RP
I consulted the cisco website about this error message and what I found was the following:C6K_PLATFORM-2.
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".

I operate between c6509-E, what did you flooding? its just packet capture gi1/3 but i dont know it and is it attack?also same seq no switch gots it?what is problem?
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 ?
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.
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.
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
I have Cisco WS-C6509 with IOS version 12.2(18)I have several vlan interface on this device.Today I create new vlan intervace
interface Vlan165 description test5 ip address 10.10.10.1 255.255.255.252 end
and vlan:
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 165 test5 active Gi7/14
But I can't ping this IP address and show ip route shows:
sh ip route 10.10.10.1 Routing entry for 10.10.10.0/24 Known via "static", distance 254, metric 0 (connected)
I have static route for this subnet /24?I can not see any error in logs, but looks like I reached vlan interface limit on this device or something like this.How can I check it?
