I going to say Layer 2 only.
A VLAN, like Cluebird alluded to earlier, is a virtual broadcast domain created on a switch. Having said that, if you were to create four VLANS on a switch, they would each individually work fine without any layer three presence on the switch. The devices on the...
When you get into the router go into config mode and type in:
"config-register 0x2102"
When you do a sh ver it will tell you whatever the config-register currently is and then right after say something like:
"Will be 0x2102 after next reload."
Reload the router and your...
2600's and 3600's are great routers that support the newer features of the IOS, but they are expensive and not as easily obtained as 2500's. If you want to learn the basics of how to configure routers (routing protocols, ACL's, QoS, etc...), the 2500 platform is more than adequate. If you have...
Cluebird,
I disagree with the part about the 2500's being useless.
Right now I'm preparing for my CCIE lab exam and have a rack comprised mostly of 2503's and 2514's.
While it is true that 2500's can't perform all of the functions the IOS has available today, it can do almost of the...
These are parts of a debug for "ppp negotiation" on a cisco router. You would see this output as an ISDN link is being established or if a serial interface is coming up. Provided they are both configured for ppp encapsulation.
Take a look at this link...
Most Cable or DSL routers have a feature called "port-fowarding" or "virtual server". This enables devices on the private side of your cable/dsl router to recieve traffic from the internet on specific ports.
Imagine you have a cisco router plugged into the private side of...
Make sure your hyperterm settings are correct. They should be:
baud rate : 9600
data bits: 8
Stop bits: 1
Parity: None
The powder blue cable is fine to use.
The router's console port defaults to these settings. Every router I have ever worked on has these defaults.

The access-list that ties into your dialer-list needs to be a numbered access-list. On each line of your access-list, tie in the time-range name. In your case, GECERLIZAMAN. The traffic in ACL 100 will be denied from being "interesting" based on the time-range tied to ACL 100...
I have 4000 router running 12.2(1d) Enterprise that can do trunking (router on a stick) on it's 10 mg E0 interface.
You can run dot.1q, but not ISL. I believe ISL encapsulation requires 100/full to operate.
I could not find a link to support this, but I'm pretty sure it's correct.

This message is letting you know that either the router's ethernet cable is not plugged into your switch/hub or that the cable that is plugged in, is not a working cable. This is a layer1/layer2 issue that has nothing to do with IP which is a layer3 protocol.
Verify your cables and switch/hub...
You can use CAR (Committed Access Rate) to rate limit traffic based on different source and destination traffic chateristics(S/D IP's, S/D TCP/UDP Ports, etc...). These would be reference in an ACL that would be referenced in your Rate-limit statement on your interface. See the below link to...
interface Serial0
<bandwidth 256*>
service-module t1 timeslots 1-24
*The bandwidth statement is only used by some routing protocols as part of a metric to determine best paths and is also used by some Qos Functions. It has no bearing on how you physical line is clocked.

You can use a crossover cable between the two CSU's. The pinout for T-1 is 1,2,4 and 5. 1 should go to 4 and 2 should go to 5. As far as timing for the T-1, make sure one is providing clocking and the other is clocking from the line. I used to do this before I got my DTE/DCE cables for my...
Adding a second static route for the same destination to a different next hop will not overwrite the current static route to that same destination. Instead the router will see two valid paths to the same destination and attempt to load balance the traffic across both links. If one of the paths...
If your WAN link is Frame Relay, take a lokk at this. Solves lots of problems.
