Careful using 3600s, the 3620 certainly isn't up to DS-3 and the 3640 will only just manage DS-3 even 100% fast-switched. Consider a 3660 or 7x00s for remote sites, certainly for the hub site. 3660s seem better for Voice than 7x00s. QoS isn't needed (Generally) for pure data, particularly if you're upgrading from T1 and there's not going to be a significant jump in bandwidth usage. For Voice, QoS will be needed if there is going to be any possibility of congestion on the line, although Custom Queueing should be sufficient. > 2.

Need your help badly > here. Depends. How much does your company rely on the intersite data links? Probably a lot. Some carriers offer ISDN dialin to the ATM cloud - this is probably expensive to set up. Another option is a Primary Rate ISDN at each site and bring up a T1-worth of ISDN if the line goes down. (Watched routes are good for this as you can build redundancy across multiple chassis at the hub site) > 3. What do I need to do if they want to use these > DS-3 for AVVID. What type of QoS, CoS, AAL1 or AAL2? AAL1 is for circuit emulation - good if you're emulating a T1 trunk for the phone system between sites. With T3 worth of bandwidth, this may not be a noticable hit in bandwidth at all. OTOH, if you want the most out of your bandwidth then it may be best to have voice cards in the 3660s at remote sites and do VoATM, which does it's own QoS. You will probably have to buy an additional PVC from the telco for differing QoS but I'm not familiar with US telco pricing. > What type of Backup should I use if we implement > AVVID?

One thing to bear in mind about this is that if hosts C and D use up all the bandwidth, no other traffic will get through. If this isn't what you want and you want to limit how much of the bandwidth they can use, you might like to look at custom queueing instead. The command you want is the interface mode configuration command "prority-list". Something like: Router(config-if)#prioity-list 1 protocol ip medium 101 Router(config)#access-list 101 permit ip host 60.100.0.10 host 199.100.0.10 Router(config)#access-list 101 permit host 199.100.0.10 host 60.100.0.10 Router(config)#access-list 101 deny ip any any -- Ryan O'Connell - <[EMAIL PROTECTED]> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Depends on the root bridge configuration and topology. If the configuration of the switch this switch is connected to is default and both ports are conneted to the same switch, port 1/2 wins. (Lowest port ID, calculated as port priority plus the port slot/number. Default priority is 32) Port cost is added outbound, not inbound, so the port cost on this switch is irrelevant. If you really meant that the received port costs are 10 and 20, rather than the locally set costs, the answer is 1/1 as lower cost wins. -- Ryan O'Connell - <[EMAIL PROTECTED]> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
