voice and 802.11b [7:45342]
Can we use voice through Wireless Ethernet Bridge (like cisco Aironet )? Is is possible to use voice if two cisco router having voice module and FXO/FXS are placed on two location connected through wireless bridge? I read that 802.11b has a drawback of lack of interoperability with voice devies. regards -- ___ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=45342t=45342 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
help required in configuring frame relay traffic shaping [7:44394]
Hello Can anybody tell me any mistake or missing configuration for frame relay traffc shaping? I connected two cisco 2600 router serial interfaces throug 32 k link. I configured point to point frame relay subinterface on both interfaces. I want to use this link on CIR 16k and peak rate 32k. My configuration is On interface frame-ralay traffic shaping and on subinterface frame-relay class cisco and for map-class map-class frame-relay cisco frame-ralay traffic-rate 16000 32000 frame-relay adaptive-shaping becn and I also tried map-class frame-relay cisco frame-ralay cir 16000 frame-relay bc 2000 frame-relay be 2000 frame-relay adaptive-shaping becn Problem is that when I run data on line e.g. file transfer, bandwidth uses always 16k or less although no other data run on ckt and total available bandwidth is 32 k. The data rate does not reach to peak rate and if I remove traffic shaping then total 32 k used. Is any missing parameter or command in above configuration? regards Khurrum -- ___ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=44394t=44394 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
STRANGE PROBLEM in updating EIGRP routes [7:37055]
Dear All I am facing a strange problem in 1751 routers. In a simple scenario in which two 1751 are connected with over a channel with serial port and eigrp is used for routing. Router 1 s 0/0 ip addr 192.168.10.1 fe 0/0 ip addr 192.168.1.1 Router 2 s 0/0 ip addr 192.168.10.2 fe 0/0 ip addr 192.168.2.1 both router get the routes of remote LAN and any machine on 192.168.1.0 (R1) network ping all machines on other 192.168.2.0 (R2) network. Configurtion on both routers have been saved. But the Promlem is that when any one of the router reboot/power cycle then it do not send its routes to other router but gets the routes of remote router and also it shows other router as eigrp neighbor. It means that when R1 reload/power cycle then after comleting reload it shows routes of 192.168.2.0 but R2 remote router does not shows route of 192.168.1.0. Eigrp configuration is present on both routers and both routers shows other router as their eigrp neighbor. Both routers shows Eigrp configuraton in sh run configuration To solve this problem, eigrp configuration has to be removed from R1 and reconfigured then it becomes OK. no router eigrp 100 router eigrp 100 network 192.168.10.0 network 192.168.1.0 Is anybody knows about this problem? Is there any bug in IOS? The router configuration is very simple and working perfectly on other 2500 series routers.

RE: frame-relay route question [7:8217]
I already configured frame relay ietf encapsulation and lmi disable ( no keep alives). In my configuration frame relay cloud get data from s1 with dlci 26 and gives data on s1 with dlci 27. But in order to this configuration words i have to configure 2 additional route ( 26 on s1 and 17 on s0 which is not required for my configuraion). In absence of these route configuratio do not work. It means that cisco route configuration can't work if dlci's do not match and not inverse of each other. All other frame-relay switches ( like memotec, motrolla ) can works with one way route ad in absence of inverse dlci route. Hi John, When you set up your frame relay network you have to be sure to give your interface a dlci and tell it where to go...like you have below...s0 use dlci 16 to the frame cloud which uses dlci 26 to get to s1. But then you have to tell s1 that it needs to use dlci 26 to get back to the frame cloud which uses dlci 16 to get back to s0. What you have is serial 1 send down dlci 27 to the frame cloud and forward down s0 on dlci 17. If you do an show frame pvc on the routers attached on s1 and s0 you will see that one has dlci 16 assigned and the other has dlci 27 assigned. But the frame is trying to send data to them on dlci 26 and dlci 17 which they dont know about. so you just need to make sure that your dlci's match and that are an inverse of each other.

So at main site a Frame Relay switch is used to switch data from TX and RX path to DTE device ( e.g Cisco router).

The configuration used is at main site subinterfaces are reated for each remote site and set specific interface dlci for each subinterface).

Problem with Console Port
Hi all , I am facing a problem with my 2501 router. It was working fine, but forthe lasttwoweeks I am not able to connect to the console port of therouter. It shows nothing on the screen when I try to connect and pressenter. When I checked the Signal level of the console port on my Break Outbox, it showed me the continuous LOW status of TxD signal. When I reboot therouter, it shows me the startup messages and finally after showing all thosemessages it hangs and TAKES NO INPUT from the HYPER TERMINAL. Ihave also tried many terminal Software like Telix, Teraterm but response of the router remains the same. There is no problem in Console Cable as cable is working fine on other Routers. The router has no prior configurations (as I did an ERASE STARTUPCONFIGURATION before), so I am not able to connect via TELNET or AUX port. Before doing ERASE STARTUP CONFIGURATION, I was connecting to reouter with AUX Port and did my configuration but after erase NVRAM, AUX was shut and router becomes useless. Is there any way out???Can I replace NVRAM of this router with any other NVRAM having configuration and then connect with the router with AUX port or via TELNET? Is NVRAM Of 2501 router replaceable? Please help me if anybody has the solution. Khurrum
