We have a site that is currently using a Contivity 1100 over a T1. They have maxed out their bandwidth and are still growing so it is time to look at a circuit upgrade. I was planning on bumping them to a Contivity 1750 and a frac T3, but everyone keeps offering us bonded T1s. I always thought...

I have several old Cisco 2600 routers sitting unused in my lab. I also have a need for some sort of term server to manage multiple devices over one phone line at my Branch office locations. Is it feasible to take the 2600 and put an Asynch card in it to create this?

Currently our COntivity 2700 is running parallel to our PIX FW. The 2700 accepts both BoTs and remote user tunnels. I was not involved in the initial design of the VPN setup and was just wondering if it would be more secure to have the Contivity sit behind our FW instead. Of course then I would...

I am studying for my CCNA and I have a couple of old 2924XL switches that I am using along with two 2600 routers. I have a CCO account through work, but am having problems finding updated code for the switches (havn't tried the routers yet). Will I be able to access code for these even though...

Is it possible to have two separate tunnels between two Contivity boxes? I have a point to point T1 connection to one of our remote offices. I would like to put a contivity at the remote site on the other end of the T1. However, the site requires a separate lab network. Traffic on this network...

I have two 2600 routers that I want to set up in a lab environment. I am hoping to take the CCNA in the next month or so. What type of cable do I need to connect the two T1 interfaces (RJ-45) to emulate a serial connection. I want to be able to set up frame relay etc. I have done this several...

I have a branch office that I am looking into replacing with Cisco equipment. Currently it is set up using Nortel ARN's as well as a direct T1 connection to our 7204 border router. The ARN's connect to each other and our border router connects (via the direct T1) to a Nortel AN router. I am...

I am receiving unusual traps from one of our BPS 2000s. The switch log shows "Trap: s5CrtProblem". I can't find any reference as to what this indicates. Has anyone else seen this before?

I have been asked to implement policy inforcement on our remote VPN users. I need to be able to verify that users have up to date virus protection and the latest Windows Updates. Tunnel Guard seems to do this. However, the more I plan this out the more complex it seems to get. Does anyone use...

We have two 7204s for our border routers. The routers are connected to a Nortel Passport 8600 (layer 3 switch) and we have a PIX FW also off the switch. When I run a continous ping from our internal network to our dmz network on the router I am getting spikes in ping times. I have seen this...

I have been asked by my security team if it is possible to require that remote users have certain software (virus protection, latest windows updates et) before allowing them onto the Contitivy switch. I know you can require a certain level of code for the Contivity client, but have never heard...

Out PIX fw uses line numbers in its ACLs. Is this possible on Cisco routers? We have two 7204s running 12.2(19a) code. We have a very large inbound ACL and it would make my life a lot easier to use sequence/line numbers. What code version do you have to be running to use line numbers for your ACLs?

We have two 7204s that are plugged into a Nortel Passport (layer 3 switch). The port on the switch that the routers are connected to is taking InDiscards. I am trying to discover what traffic is being discarded and why. I have been working with Nortel and they have suggested checking for CDP...

I have a contivity 110 that I have just set up at my house. The purpose of this is to allow branch tunnel connectivity to the office so I have easy access to the network 24/7. I have the stateful FW on it, but am not real sure how to configure it. Ideally I would like stateful Internet access...

Is there a way to see the MTU setting on either the Baystack 450 or BPS 2000 switches?

Just wondering if anyone is running the most recent version of code on their Contivity. It looks like I am going to have to upgrade again in order to implement VLANs and before going to the newest version (v05_05.121) thought I would get any info on potential problems etc. Thanks!

I have a Passport 8600 and I have recently noticed spikes in response time to our Border routers. We have 2 7204s directly connected to our Passport. Both are in the same VLAN and are hardcoded to 100-full. Pings times from the passport to the routers spike as high at 180+ms at times. I see no...

Just want to be sure I am reading this trace file correctly. I have a sequence that goes like this: - Address A send Address B a TCP retransmission [FIN, ACK] with reference time of 40.6854 seq=0 ack=0 - Address A send Address B a TCP retransmission [FIN, ACK] with reference time of 83.8881...

Can the BPS2ks and Baystack 450s do LACP? If I have a non-Nortel device on the other end of a trunk from a BPS or Baystack, do I use LACP?

We are looking at possibly implementing SSL VPNs sometime in the future and are looking at either adding the SSL module to our Contivity 2700 and 1700 at failover site or utilizing the Alteon SSL capibilies (we have and 2424 SSL already). Is one way better than the other? What experiences have...
