Have a problem I am trying to figure out. I am having to pass traffic through a switch that I do not fully manage that has route maps applied on the native VLAN that is used for the trunk I connect over. I have done a lot of searching but could not come up with a definitive answer for my...

In the process of writing some ACL rules, and I am trying to evaluate the existing traffic so I have some Permit IP Log statements to narrow down what normal traffic is going through that I need to write rules for, however, the logs that I am getting do not have port numbers (which I need). Is...

Is there an ethernet WIC/HWIC that supports NAT for the 2811. I have one 4 port 10/100 card but it doesn't support NAT overload.

I have View 4.5 up and running, though I have run into an issue with connectivity from outside the network. I have the View Connection server setup, and forwarded ports 80 & 443 to the view connect server inside - this is a temporary setup until we run everything through SSL VPN. I can...

Took me a few days to track down, but in the midst of configuring and troubleshooting a really complicated network transition to facilitate moving our entire datacenter to all new equipment (servers, san, switches) I ended up with a VPC link between the new Nexus switches and the old 6500 core...

I wanted to vent some frustration more than anything else, so here goes and hopefully someone else can learn from this. As a network engineer and all around geek I have a ton of hardware running around my house, and knowing it's value I have everything in my house except for lights on either...

I have someone that is looking to move their DHCP from a windows server to their Cisco Switches which is easy enough, however, they also want to retain a log of DHCP assignments so that they can track down who had what address at some point in the past if they need to (say RIAA letter or...

I thought it would be fun as a tangent to the networking gallery thread to see some extreme uptimes for devices under your control. Here are a few of mine: Storage Network Switch: (Cisco 3750G) This is the master, other switches have been added to the stack over time w/ no downtime...

I am working with some new T1's I am tuning up, and have them configured in a ppp multilink. So far everything is working fine but the ping times are ~ 40 msec, and on the old T1s (not bonded, different carrier) they were ~20msec. I should mention that this is a private site-to-site loop, no...

I need some help parsing some configs to make sure this will work from a VoIP standpoint. I have a client that has two private T1's between the central office, and an office out of state. They want to bond the T1's into a single multilink to get better bandwidth for some heavy hitting database...

I wanted to call out for some SPAM blocking recommendations, our current solution is not providing the features that we need. History: started with a barracuda 400, but had continuous reliability issues with it locking up or queuing thousands of messages. Current: Have ORF installed on...

First - Google had major outages, this is still very new so I do not know how widespread it was, but I know it affected a number of states and seemed to primary affect AT&T's network and Qwest's network (unfortunately our two ISPs at work) but not McCloud. I was fortunate to have a bunch of...

I know there are a lot of Cisco minded people lurking in the Forum, so I wanted to look for some been-there done-that experience. I need to come up with a parts list for a wireless backup between two sites in case the primary 1Gb fiber link is cut. History - there are currently two fiber...

I have a friend who is going to have a kid at their home for a while and they want to put in place web-filtering to block the obvious porn etc. The setup is 3 Mac computers (2 laptops 1 desktop) that will need to be filtered at least some of the time. Being a network/routing guy my first...

I had a laptop come in to me (briefly) that is having some really odd behavior. It came in because it would not correctly make the users profile and keeps using a "temp" "default" or ".local" for everything related to the profile. What peaked my interest is that looking at the logs...

I am expanding one of the wireless networks that I manage (doubling) and I wanted to see if there were some seasoned wireless-guru's that could offer some advice. Particularly what I am looking at is a residential network that will serve up internet access and that's it. Things I want...

I am setting up a 2811 with a 16 port switch module. I have the router and the switch module configured, and everything seems to be working just fine (ping end to end). I want to know if I can use the second built in Gig port as a switched interface accessible by the other servers on the...

Question for you all: I am doing some consulting and the customer bought a router off eBay that they wanted me to configure that is toast. The console ports are completely dead. Breakout shows no voltage anywhere. They want to get their CoLo up & running ASAP, and I happen to have the...

If you have two interfaces on a router that are part of the same subnet, does the router prevent broadcasts from one interface from going through to the other, or is the broadcast domain unchanged. Example: Router running a L3 routing protocol, int e0 192.168.10.1/24, int e1 192.168.10.2/24...

I upgraded to 7.10 and it changed the device name of my wireless card from eth2 to eth0_rename. Any thoughts on how I can change it back, or at least get rid of the _rename?

I need a quick and dirty on how RADIUS is setup / works. Specifically I am working with steel-belted-radius, which is now owned by Juniper. Currently we use RADIUS in authenticating our wireless clients, but that is it. I want to get all of our networking devices to use RADIUS as the primary...

I just finished up my CCNP, and was wondering about a spanning tree issue that I am seeing in a network. Layout is: Access Switch A ---------------Core Switch B--------------Access Switch C (Root Bridge) .................................................|...

I haven't done much with Jumbo Frames yet, so I am wondering if this output is normal .... are "too large frames" and "valid frames, too large" just Cisco's way of saying you have an MTU > 1500? #sh controllers ethernet-controller gi1/0/1 Transmit GigabitEthernet1/0/1...
