Just got done reading about nested QOS maps and one blurb I read indicated one should be careful not to define a catch all "IP Any Any" ACL for the default class. They sited that the reason was you would then exclude all your routing protocol traffic like BGP and EIGRP, etc. They suggested if...

is there anything special I should do to get the 3925 to see the wic 1am installed in slot 0? I put it in there (system was turned off) but after boot, I can't grab that async interface to configure it. It doesn't show up. with T1 wics you have to issue a card type but I've never had to do...

say you have this in your route table: Gateway of last resort is 10.8.1.1 to network 0.0.0.0 137.135.0.0/16 is variably subnetted, 2 subnets, 2 masks S 137.135.128.0/24 [1/0] via 10.8.1.1 C 137.135.128.0/23 is directly connected, FastEthernet0/0 10.0.0.0/16 is subnetted...

want to set up the sla measuring feature of the cisco product line on my switches in each branch office. Have a linux server set up just to be the counter part. has simple web server, dns, dhcp and allows ssh just for the switch SLAs to 'hit'. This gives me a unit that, because this is all it...

Anyone ever seen this with 3750 stack? I have 2 3750's in a stack, suddenly they appeared to reboot...traffic frozen, devices unable to respond to the ping tool that monitors them...looked at the stack..all amber lights as you see on a power up. The show ver says the stack has been up over 5...

has anyone had cables that were bad but which did not produce physical (as in layer 1 or 2 type errors) on the switch? I know a bad cable can cause retransmissions and such but wouldn't you expect to see errors recorded on the switch if you had a bad cable? I'm about to replace a really hard...

every now and again I get a cryptic snmp trap send from an old 4506 switch. I've run through Cisco's mib navigator and as near as I can tell, it's from the TTY trap set. But the trap contents don't tell me squat! When I read up on the TTY trap itself it said that the implication is a TCP...

Has anyone ever tried using muti-track options on a cisco switch running advanced IP services? We really need to get this feature to work. I have both 3750's that sit at the core of branch offices, with 2 routers hanging off them, each router connected to a different provider for MPLS...

(big hole in wall where I've been slamming my head into it) I have two providers between site A and site B, each an MPLS network. We have a switch between each router, one at each site. EIGRP load balances most traffic for us. We prefer provider 1 for time sensitive traffic (voice and video)...

what would make a switch or a router arp over and over, 6 - 10 seconds apart, for the same IP address? Using wireshark I see my core switch arping for say, 10.1.3.117 and it will do so about a dozen times in a row in rapid succession then quit. Later I'll see the same thing for another IP...

I am working with an inherited set up. In the beginning there were 3 offices, connected with dark fiber, like so: 6513 / \\ / \\ 4509 6509 There were 2 fiber runs port-channeled to the 6509 and 1 fiber to the 4509. The predecessor, instead of giving...

working with package called Epager enterprise; does snmp trap managment. Unlike WUG I can't compile my own mibs in, I have to send them to the company and they send me back a compiled database. They do it free, that's not the problem. But getting the right mib is not easy. Cisco breaks them...

can you configure the MS dhcp server (on server 2003) to give out domain controller information? We have users across an MPLS network complaining about horrible slow logins. When I trapped packets I found they were connecting to a server on the other side of the WAN for DC services. When I...

I haven't read anything that says you can set a port to more than one vlan. You can make it a 'trunk port' to pickup some or all of your vlans...but...isn't a 'trunk' by definition supposed to hook two switches together? Here's the deal: our security team just invested in a product called...

I'm trapping a problem with replication between our on-site and off-site san. The data goes from the onsite san, across a fiber-scsi to ethernet switch, over dark fiber to the offsite location, across another ethernet to fiber-scsi switch and onto the off-site san. The fiber to ethernet switch...

Grr sometimes I have this big block on my head. Math wasn't my strongest suit ever... I understand the EIGRP forumla to calculate FD. BUT my situation is I need to come up with the values for bandwidth and delay such that, when load balanced, the ratio = 3.4. For the life of me I can't make...

our telecome group has purchased Polycom 7000 VTC HD units. The quality of the calls between two offices in the same building is great. Between units at opposite ends of our MPLS it is not so great. It can appear to be fine during tests and then when we go live it's all pixelated. The...

IS anyone using this product and if so, I wonder if you are having the same issues we are. Occassionally, for no reason I can discern, this thing just gets wadded up and starts putting packets on the wire that have the same source mac address as our firewall. When that happens, packets begin...

Every day I see something new in this place. Today I was trying to understand the way my predecessor hooked up a bunch of VMware boxes. These boxes have about 7 or 8 cables each (8 if they are HP/Compaq due to ILO port being hooked up; 7 if they are Dell for lack of same). Anyway there is one...

I have been tasked by my client to identify and mark all the cabling in their server room. Seven years and no one marked a thing or put a desc in the switch port config. I first thought it would not be so bad, using show mac address and show arp would give port-->Mac add-->IP address then all...
