Cisco WAN :: 6500 Bgp Hold Timer
Apr 26, 2013
We have a non-cisco device peering with Cisco 6500 for bgp. The routing table is fully populated and connection is good.But after some time we see bgp hold timer error on the non-cisco device. This device by default has a hold timer of 90 seconds which is different from default cisco hold timer. Will this cause any disruptions to the network? If we change the hold timer on one device to match on both sides, will it reset the bgp session?

I am working on a wlc 5508 in a lab environment doing snmp reporting & i was wondering if there is anyway to after the timing on how quick the snmp traps appear on the trap log page? I have looked through the gui but cant seem to find anything, so not too sure if there is a cli command, the traps come in very quickly on the nms way before they appear on the trap log page.

I have a working BGP session established. With "debug ip bgp events" I see many (2/3 every second) messages like this:
*Jul 23 11:23:48.773: BGP: default originate timer at max delay of 64 sec
*Jul 23 11:23:48.997: BGP: default originate timer at max delay of 64 sec
I can find nothing about this message. IOS version is 12.4(24)T and platform is Cisco 2811

I am having a very peculiar issue wherein an 1142 WAP is randomly disassociating and powering down due to what the Trap log is calling a "Watchdog Timer Reset." The only way I can get it back up is to power cycle the AP. Currently the AP is being powered by a Cisco Power Injector. Is this a hardware of software issue with the AP itself? From what I read about Watchdog Timers it sounds like it could be. I posted below the Trap Log output after I power cycled the AP:

it's possible to implement that on any Cisco Wireless Devices, so All I need is create one wireless account with timer for 1 hour, so SSID as guest without any password and once you connected it works only for 1 hour then disconnects and you can't connect again. Then create second account where you can browse timelessly but you need a password to connect there.
1. Is it possible to do that using one or two SSID, or password changes?
2. Is it possible to do that on Wireless controller WLC2100 series, or AP1000, AP1100 series, or AP500 series?

I have a strange issue with clients connected to a WiFi network.I have configured AP in FlexConnect mode and 2 SSID's. After a reboot of the AP the network is stable for almost 45 mins. Then each client will go UP and Down, mostly with a delay of 5 mins.
What could be the source of this. The clients are Windows CE handheld with fixed IP adres. I already configure persitent client and have play arround with APR timers as well. Thereby an Windows desktop or an iPad has less connectivity issues but even they expert pakcteloss once in severall minutes.
Session timer is turned off
The iPad for example can play music, but each 5 mins you hear a little hickup and 2 subsecond ping are loss.
Controller version is 7.3

I am having an issue on a Cisco 3750 stack where when the stack master is rebooted, all my lacp port-channels drop and then come back up again. After doing some investigation It seems that it is happening because of lacp using the stack master mac-address as part of the system-id, so when the stack master reboots, the stack mac changes. I see that there is the command: stack-mac persistent timer 0
There is this warning about using this command:
When you configure this feature, a warning message displays the consequences of your configuration. You should use this feature cautiously. Using the old master MAC address elsewhere in the domain could result in lost traffic.
My question are:
Are there any other consequences to using this command (apart from moving the switch/mac to another location in the network)It mentions 'If the entire switch stack reloads, it acquires the MAC address of the master as the stack MAC address' Is this still the case if you have the stack-mac persistent timer to 0? Does using channel-group mode on for the port-channels still use the same mechanism of having a system-id? (Will the channels flap using 'mode on' when rebooting the stack master.

I'm running Windows 7 Home Premium, and using a ASUS USB-N13 Adapter to connect to my ASUS RT-N16 Router. I am able to connect to the network with no problems, however every 10-15 minutes I will be disconnected. I am almost positive the issue is with this computer or the adapter, because I have no wireless connectivity problems with my xbox.After being disconnected, there are 2 ways that I get the connection back. I either:1. Right click the windows wireless network icon (bottom right) and click troubleshoot problems. This seems to turn the adapter on and off during the automated troubleshooting and is then usually able to connect.2. In the ASUS software, I click "IP Renew" and this can sometimes fix the problem.Sometimes I am able to stay connected for hours, while other times it disconnects every few minutes. I have no idea what the problem is, and I know my way around computers pretty well but I am not well versed in networking.

I am trying to figure out how this works. I have an ISP device that connects to my 1841. ISP and fa0/0 hold the /30 WAN addresses. Fa0/1 hold one of the public IPs, lets say 1.1.1.1/29. Then the outside interface of the ASA holds 1.1.1.2/29. Now I have two routes in the 1841, one for default route going back to the ISP device, and a route for the 1.1.1.0/29 network going to the ASA.Now I have 4 more publics I can use 1.1.1.3 - 6. I do not want to assign these IPs to the servers, but yet just NAT them. I know this is possible, but cant figureI took an internal host and did a one to one static NAT from private to public. Packet tracer says my NAT rules are ok. Allowed all IP traffic for testing and still can't ping the server.

The computer has a strange habit of dropping my internet connection after it's been turned on for a while. I've already checked to make sure that the setting which allows windows to turn the wireless adapter off to save power is disabled, and I've set my laptop up to use a static IP address which no other device should be using. I'm connecting via wifi.The only way I know to fix the problem is to restart the computer whenever the problem presents itself.I have a motorola surfboard modem and a linksys e1000 router.The computer always says that I am connected and that I have full signal, but it displays an exclamation point over the internet icon saying 'no network access'

Using a wireless connection, my PS3 struggles to hold the connection. It either times out trying to sign on to PSN or EA sports, or connects only to lose the connection shortly thereafter. My router is the AC1000 and I'm wondering if there is a specific setting that is required in the setup that I'm not aware of. My connections to all other devices are solid.

one last try before boxing up my new DIR-655 and taking it back to Microcenter. I've opened a case via email and got the standard response, below.I have a Dlink DP-300U print server that works fine with my 'old' Belkin router, a F5D-7230-4 wireless unit. Nothing wrong with the Belkin, I'm just getting some service drops from my lousy AT&T ifitl 1.5mbps ISP and thought a new router might work. I actually read the manual (!!) before installing the DIR-655 and even followed it. The print server just isn't visible on the network. Everything else is, though. The 'suggestions' from Dlink tech support below are very useful. If I could 'see' the print server to verify its IP address, we wouldn't be having this conversation. I've rebooted everything, several times and even reinstalled my old Belkin router (which always sees the print server.) And Dlink, no...I'm not interested in paying you $32.95 for up to a half hour to maybe fix a problem caused by your new device. And dropping my call after almost 15 minutes on hold is not cool, either. With reference to the issue you are facing, we suggest you to kindly ensure that the IP address assigned to DP-300U print server is in the same network range as that of your DIR-655.
NOTE: The default IP address of DIR-655 is 192.168.0.1 Once it is done, try to ping the IP address of DP-300U using any of the wired / wireless client connected to DIR-655.note the DP-300U is not currently supported in North America. D-Link offers a premium fee based support line that will be able to support any issues you have with this product.

Blocking Ports don´t send BPDUs, but they can receive them from designated ports.Blocking ports, can it hold BPDUs?
I think that Blocking Ports only receive, analyse and then discard the BPDU.But, what happen if the blocking port receive a better o worse BPDU? in this case, must be the bpdu stored?

I have a win 7 netbook that I recently got and for some reason it suddenly cannot keep a connection to the internet. It used to keep a connection before but now I keep getting the error the default gateway is not available about every ten minutes while connected which of course is very frustrating.
I've tried updating all associated drivers but apparently that hasn't changed anything. I've tried restarting the computer and tried different connections. I know its nothing to do with the internet connection I'm trying to connect to as other devices are able to keep a connection with no issue.

My wireless on my computer won't hold a connection for any longer than 30 minutes. I've checked the drivers, the wireless router, and scanned for viruses (several times) but nothing seems to work. In the last three months, I think I only had one occasion where the connection remained stable for longer than an hour. It doesn't matter what router I use or where I am. It has to be my computer.
I have a Compaq Presario CQ57 and I have had it for about 6 months.

My E3200 is having issues with keeping the speed up on wireless G. I'm about 20 feet away from the E3200 and there is 1 6in wall between me and the E3200. My connection will not hold 54Mbps, its constantly dropping to 36Mbps, even down to 5.5Mbps faily often. Around 30 feet away there i will lose internet connection yet my laptop says excellent connection to wireless.

I have 1841, 2800 and 3800 routers and need to do IOS upgrade to all of them. Existing routers do not have enough flash to hold 2 IOS images.if the router has 12.4.13r ROM IOS, will I be able to boot the ISR router via Cisco brand USB? That means in case something goes wrong while I am uploading new IOS to the router via WAN and something wrong, now router in ROMMON mode. If a local site person has a Cisco USB with an IOS in it, can he just stick it to the router and reboot the router and router will go out of rommon and go into normal mode? After it is working, then I can put the running IOS onto the exisitng CF card so now I can remove the USB and the CF card has a good IOS and reboot the router again.I am just trying to find a safe way to upgrade the site when they don't have big enough flash to hold 2 IOS at the same time. The local person is not technical so asking him to setup tftp server and put the IOS in the computer and so I can do tftpdnld while in rommon mode to grab the IOS from his tftp will be difficult to have the local person to set it up.
If ISR can boot off of the IOS in USB only, then I assume the requiremetn is the ROM IOS needs to be 12.4.13r. Then what is a safe way to upgrade the ROM IOS to this then? I never upgrade ROM IOS before so don't know what kind of problem I may run into and whether it's higher risk to upgrade this than upgrading the regular ios? If it is, then all my routers won't have this ROM IOS version, so that means I can't use USB to boot then? Will that means I am down to tftp server option? ( I heard xmodem won't work as it will time out before the ios can load via the slow dialup link into the router to rescue it from rommon mode).

Comcast had us unplug our modem in order to upgrade to their new faster speed. now our wireless router won't work. We've reset the router twice. we can set up the wireless network but we cannot connect to it. The connection last for about 5 minutes and then we get an error, cannot read IP address. Comcast says it is not their problem and linksys says they can't assist either.

SG200-08 and SG200-08P fail to hold or update Date/Time.(New installation for a UC320 setup.)I've got both an SG200-08 and SG200-08P that are failing to maintain date/time when set with "Use Local Settings". Every restart/powercycle causes them to reset to Dec 31 1969. Other settings save fine.I first tried to set time via SNTP Unicast using a variety of public time server addresses including the 3 hard coded to the SG200-08 firmware:
Sadly though it always just shows "Active Server Server Host Address: 0.0.0.0" and continues having 12/31/1969 as the date. Both after a config save and a reboot.I can ping the NTP servers just fine from the switches either by IP or by hostname.At this point I've decided that I must be missing something simple. At least I hope so... otherwise it's a firmware bug which means waiting for a fix.Other devices behind the same firewall/gateway (RVS4000) are updating NTP

We checked the disc (hardware) with an Ontrack-tool -it is OK.

I have a question with regards to 6500 Redundancy. We currently have only one in our DC, it has 2 SUP 720s, two FWSMS, and multiple switchport blades. My question is is this fully redundant? and if not what is it that can fail, so I can look into adding that extra layer of redundancy.

I've been studying the PFC and MSFC features on the Cisco 6500 and came across a very interesting fact that on a Cisco 6500 switch ACL entries that are processed in hardware do not show any matches when we use the show access-list "acl name: command. From what I've read so far I've come accorss the command to check the ACL hit counters fro entries that are processed in hardware.
Below is the ACL counter from Hardware and the Software and I have also attached the entire ACL.
Output 1 (Hardware Matches)
