ISRG2 (c2951-universalk9-mz.SPA.152-4.M1.bin) has 512 MB of DRAM. Periodically it runs out of memory: [code]
1. Why "show process mean" command shows less memory than 512 MB? Processor Pool (248 MB) + I/O Pool (58 MB) ~ 310 MB only?
2. *Init* process holds more memory than normal (202 MB). What may cause this?
I was wondering to understand if there is an specific license in order to enable NBAR2 in my ISRG2 892 with IOS 15.2(3)T. If not, what is the basic license I need to have for NBAR2 ?

View 1 Replies View RelatedWe have created a sample configuration for ISRG2 2901 Router. The sample configuration is long, and with copy/paste it is possible to skip some lines, and it is difficult to ensure the configuration of every device is standardized due to this error possibility. What we are trying to achieve is first create a template from this sample configuration file, and then create configuration files for each device seperately and automatically. After creating this configuration instances, we want to be able to distribute the configuration files (and possibly the ios) to the devices during the staging phase. Since there are about 1000 2901 routers, creating configuration files is important?
From searching we have found the following tools:
1) CCE (Cisco Configuration Engine): This tool seems to be very efficient for distributing the created configuration files. We may use the serial number of the device, and it provides almost zero touch provisioning of the configuration files to the devices. Creating the configuration file from the template seems to be manual, i.e enter the ip addresses of the interfaces, the routing tables one by one for each device. How can we use velocity template for device configs?
2) Ciscoworks LMS Prime: It is possible to create a baseline template for the devices, and after getting the backup configuration of the routers, it is possible to compare the actual configuration of the device with the baseline template, and understand if there is any difference with each other. This is indeed very useful in order to keep the configuration standardized, we again could not find a way to create bulk configuration files from the baseline template.
3) Solarwinds Config Generator: This tool is useful for creating a configuration file from a template, but again not for automatically creating configuration files, and needs manual intervention.
4) Excel Macro: It seems that some people have achived to automatically create configuration files with using an excel macro, but we could not find a procedure or tip of how to achieving this.
5) Pearl or TCL/TK Script: Again since we are not software developers but from networking field, it is difficult to achieve a working form of this scripts or codes due to to lack of documentation and development experience.
we have an RV082 router that a few days ago started restarting itself after normal usage.The simpton is that when people come to office, starting using the Internet the RV082 resets. It stays online for 3 to 12 minutes and then it resets again.
clicking on Reset to Factory Default in the web interfaceafter the reset, I confirmed that it was reset to factory default I reset it again using the reset buttomre-configure the RV082 manually.I also tested with another identical rv082 (hw version and firmware version) and after doing a backup of the config of the original rv082 and restoring it in the new rv082, the same problem happends.

View 4 Replies View RelatedI am currently using a 5508 Cisco WLC with software version 6.0.196.0. It has been running smoothly for the past 1.5 years, but have recently discovered that the WLC will randomly restarts itself. I know this because I have seen the disruptions in our wireless network, as well as seen the Up time counter reset itself. I have tried looking at the trap logs to see if there is any significant network traffic that may be causing this, but from what I can tell there is nothing out of the ordinary. The restarts happen randomly at random times. I have never seen a Cisco device behave this way, not a switch, a router or security appliance for that fact. What may be causing the WLC to just reboot itself?

As indicated in the subject, wireless users are finding that it is either unattachable (shows up in the list but fails to attach) or if you manage to authenticate and get in, it's painfully slow or simply drops out. Security is WPA-PSK. Only noticed the issue after a couple of Windows 8 laptops came into the household, but the problem still seems to be there when they are off so not sure if they are connected in some way or not. Updated to the latest firmware - no change. Wired connections are fine and when it's initially restarted, so is the wireless, seems to happen sometime after wireless services are restarted. Only the one Wireless SSID, nothing fancy, max users around 5, all on laptops or the odd pad. I changed channels done narrow wide etc, (using mixed mode - some Wireless N laptops some Wireless B/G. Nothing seems to make any difference. No log entries until the Wireless system is restarted, doesn't require a reboot of the router, just a SUBMIT of the existing wireless settings to force it to restart.
I have a problem where the complete home network disconnects whenever my computer reboots from idle state (either after leaving it for a while so it goes on sleep, or by putting it on sleep mode). It then takes a few (long) minutes for the network, and the internet access to it to reconnect. In the meantime ALL devices in the house (other laptops, ipads etc) lose connection too. It's only my computer which does this, so i'm assuming that there's something wrong with the settings on computer.

I have recently purchases a Cisco srp547w for my organisation. It is working fine with one SSID enabled. I have configured everything with no problems using the Web interface. However, whenever I click the Edit button, in the Security column, in the Wireless Table under Basic Wireless Settings I get a pop up message which says :"Some values have been changed. The router must restart the wireless module to take effect.Please wait several seconds" I have tried this using 3 different browsers and get the same behaviour in each browser.

Using a Cisco 2921 router with an RPS 2300, I came across a table in the 2900 Hardware Installation Guide that I can hardly believe: table 5-3 seems to tell me that in order to back up ONE 2921 with RPS power, I will need an RPS with TWO 750 Watt or TWO 1150 Watt power supplies. Is it really true that I need to throw at least 1500 Watts of backup power at a router that has a main power supply of approx 300 W?
View 13 Replies View RelatedI need a router to connect to our ISP by BGP and in a future to a second ISP. Our ISP is going to provide us about 300.000 route entries by BGP. So router 2921 would be enough??? or should i go to a higher model?We are going to have 100Mbps with this ISP and probably in 3 months we'll have to double it. Also we'll need IPv6 support.I saw router performance [URL]f and it's has 480.000 PPS and 245 Mbps but for 64 bytes lenght packages. If the packets are bigger the throughput should be best I suppose... 1500 bytes about 5,5 Gbps. In the case you consider the model is sufficient, the flash or RAM should be increased?
View 4 Replies View Relatedi have one interesting problem with local PBR on 2921 router. Here is the case,On HQ site there is 2921 router with two directly connected ISP, and there is Branch which is connected to only one ISP. The configuration should be to connect HQ router to Branch router with two VTI tunnels, so that each tunnel on HQ site should be terminated on different ISP, and EIGRP will be monitoring each VTI status.The problem is on HQ site, there is only one way to specify router with LOCAL PBR configuration, so router should send on ISP1 terminated tunnel traffic to ISP1, and on ISP2 interface terminated tunnel traffic to ISP2.
As I know this configuratino should work, but I could't make it work on c2900-universalk9-mz.SPA.151-4.M4.bin IOS, and on c2900-universalk9-mz.SPA.152-2.T1.bin.
Here is simple config:
ISP1 ip is 1.1.1.1
ISP2 ip is 2.2.2.2
3.3.3.3 is Branch ip address.
!
ip vrf BRANCH

when I configure one default static route, it starts workig, but both tunnels go with specified ISP, and also there is no vrf problem,when there is no any vrf config it also don't work. gre tunnels also dont work.

I am trying to set up a new router for training.I am attempting to my First BGP multihome.
The router is a 2921.We have a bonded t1 line and a metro ethernet connection
we have 2 /24 networks 1 /23 and 1 ipv6 /48 ,Behind the cisco router we have 3 Open BSD firewall Pairs, that are used to segment the networks into the production, development and my lab.
one of the /24 and the ipv6 block are veriably subneted, these are the routes that I am having troubles with.I am attempting to aggregrate the /24 and the ipv6 block to go out to the internet.
they show up in the routing table as advertised but you can not reach any hosts through the cisco router.
here is the bgp config
