hey Folks My 2621 suddenly started dropping packets...with in a span of 30 minnutes i will have like 35 input error , 35 CRC error and like 15 frame error. I know the problem might be the ethernet port on the router ..or a kink on my cable ? or the switch it is attached to. I really want to compare note with anyone who has experience this. the interface is Fastethernet 0/0 , the other fastethernet 0/1 is not like that. no error what so ever...i am wondering what went wrong all of a sudden.

The question calls for this: - - Configure cat1 and cat2 for layer 3 redundancy with HSRP for Vlan 5 - - Configure HSRP such that when both cat switches are available, traffic is load balanced across both cat switches and when one is unavailable, the other cat should take over all traffic from Vlan 5. Here's my configuration idea: Cat1: Interface Vlan 5 ip address 150.50.5.5 255.255.255.0 standby 1 ip 150.50.5.100 standby 1 priority 150 preempt standby 2 ip 150.50.5.200 standby 2 priority 155 preempt Cat2: Interface Vlan 5 ip addres 150.50.5.10 255.255.255.0 standby 1 ip 150.50.5.100 standby 1 priority 155 preempt standby 2 ip 150.50.5.200 standby 2 priority 150 preempt Cat1 will assume the role of the virtual IP 150.50.5.100 and Cat2 will assume the role of virtual IP 150.50.5.200. One would then configure the default gateways on the hosts. Half the hosts have 150.50.5.100 listed first as the D.G. and the other half would have 150.50.5.200 listed first as the D.G. Is there another way to do this? Thanks, Dale Date: Fri, 1 Nov 2002 16:15:55 GMT From: "cer" Subject: 802.1Q trunking on 2500?? [7:56690] Hi, all, Can the 2500 series support 802.1Q?

[7:56690] James, Is that doable on a 2500 series router? Basically, I want to configure something like this: Switch has VLAN 10 VLAN 20 VLAN 30 I want to set up 802.1Q trunking between the switch and 2500 such that: VLAN10 goes to Ethernet 0.10 VLAN20 goes to Ethernet 0.20 VLAN30 goes to Ethernet 0.30 Just wanted to clarify what it is that I would like to do. I just wasn't sure if the 2500 router support 802.1Q or if this can even be done.

Sorry about not replying last nite -- I ran out of time and had to take my grandchildren "trick or treatin'" -- but I appreciate all the input. First -- I am not running an access list. I just got this router (2511) and wanted to configure it, including upgrading the IOS (existing IOS 10.2(4)). Thus, I first wanted to copy the flash to the tftp server. Apparently, this is where I have gone wrong!! With my advanced age as an "excuse" -- from hyperterminal I merely typed in "copy flash tftp" and was unsucessful: TermServer>enable Password: TermServer#copy flash tftp System flash directory: File Length Name/status 1 4404136 ij10240 [4404200 bytes used, 12373016 available, 16777216 total] Address or name of remote host [GREG]? Source file name? ij10240 Destination file name [ij10240]? Verifying checksum for 'ij10240' (file # 1)... OK Copy 'ij10240' from Flash to server as 'ij10240'? [yes/no]y ..... Copy aborted - TFTP timeout TermServer# This procedure has worked flawlessly for the past couple of years. The sole difference in my network now is that I have installed a Linksys cable modem and hub (100). That being said -- I wonder if Priscilla's last theory might be the culprit. My cable-modem router runs NAT. SO I'll do some exploring and investigating and get back to all of you later today. ' Thanks again for the assistance. I know my question (at least at my level of training) may seem dumb, but as a professor I used to tell my students, "The only dumb question is the one that is NOT asked!!!" So be patient and forgive me for my apparent lack of ability to resolve this issue myself!
