I have a 892 router configured on fa0 with vlan1 and a catalist 3560. On catalist all ports are in access mode and vlan1. When I'm connecting port fa0 from router to catalist, the catalist port is shuted down What should I do on router on catalist to make the connection working ?
View 4 RepliesI'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable. It's different every time I apply the config to the same group of ports. However if I do them one at a time it seems to work. But I really don't want to configure 6 fully populated switches one port at a time. We also have a lot of 3750's and they gave me no problem using a port range. [code]

I bought refurbished Catalyst 2950. I followed all steps(even ip address and subnetmask and ..etc) guided in [URL] no thing happen, my computer doesn't connect internet. I guess switch has no routing.. Before bought that, i thought it is plug and play type. And now having some serious issue which i have to configure via telnet and/or ssh.

-Building 1: 10.2.0.0/24 (vlan20), 10.4.0.0/24 (vlan40), Internet connection
-Building 2: 10.1.0.0/24 (vlan10), 10.3.0.0/24 (vlan30)
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.
I have got a new 48port Cisco catalyst 4948 switch, which I configured as a VTP client and connected to Cisco 3750 which is a VTP Server (this switch is on production network). I connected port g1/0/48 from 3750 to port g1/48 on 4948 through a straight cable and made both ports as trunk port (I also tried through cross cable). The problem is these two switches are not detecting. For testing I connected a PC directly to one of the port on 4948 (making that a switch port) still the LED on switch didn’t glow up. Is there any special command needs to be run on 4948 switches to activate its physical ports?

I have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?

We are using catalyst 2960S Lan Base IOS on Radio towers. We just bought 50 Accest points, thas are GPS synchronized. Problem is the APs need to be connected on L2-mac betwen each other. But at this time we are using port isolation on each switch (tower) by protected port function to isolate clients from each other.
My question is, is possible to specifi a Mac addresses in specific vlan thats can comunicate betwen protected ports? On tower is one Master unit and others are slave. I thing there is only 1 dirrection comunication - from master to slave.
I want to configure switch port bandwidth limit for my Catalyst 2960-48, is there any hardware / ios limitation? can I configure it at all 48 switch ports?

5.- In the show running-config not appear configured Po4A and Po4B. it only show on outputs
6.- Po4A and Po4 was not configured on neither switches, my question is why appear Po4A and Po4B on switch-1 and switch-2 respectively? and why Po4 appear in down down.
7.- I solved this issue by shutdown and not shutdown to the interfaces on both routers, currently all is OK.

View 8 Replies View RelatedI have connected a 10BaseT device to a CISCO Catalyst 3560xPOE switch with dynamic port security. All seems to work fine when the distance between the two devices is closer then 200ft. When I connect to 10BaseT devices farther out near 300ft the response from the attached device is lost. It works ok on unmanaged switches at the longer distance. Is there a minimum response time from attached devices for dynamic port security to work properly? Is there any other explanation why it would work on cheaper switches, but not on the Port Secured Switch?

I am in the process of swapping out an older 24 port Cisco catalyst 3525 POE switch running IOS 12.0(5) with a 48 port POE catalyst 3560 running ios 12.2(50)The trunk port on the older switch (that currently works) is in port Gig0/1 with as basic of a trunk config as you might find.
In the newer switch I have a 1000BaseSX SFP min gbic with a SC-LC fiber cable attached (8.3/125 – 15 meter.When I make the connections, I get no lights… no connection.
I recently installed a cisco 2901 router. The router is connected to hosts using a SG 200-50 50-Port Gigabit Smart Switch
Problem is the router internal interface keeps shutting down without notice and randomly. At that time I cannot ping the interrface from a LAN PC even though I can ping other hosts on the LAN. The ISP link is okay since I can put a static IP on my computer and access the net.
How I can shutdown a module when I am running vsl.I can use the following command #hw-module module 2 shutdown.As I have modules in both switch 1 and switch 2 how can I ensure I only shut down module 2 in switch 1.

View 3 Replies View RelatedWAN link plugs into a 2821 Router with an switch module in it. About 8 clients are plugged in to the 2821.2821 connects to super cheap netgear switch (I'm 99% sure it's stripping dot1q headers) via one of the ports in the switch module. About 4 people are connected to the netgear.Now, I sent a catalyst 3560g to the branch because they wanted to extend into a new building. Someone decided to run a single cable from the netgear to the 3560. On the 3560, I have about 5 clients and a couple of APs.
So it goes 2821 -> Netgear -> 3560. All of these are single connections.When the 3560 gets plugged in, all clients on the netgear lose their connection, and nothing on the 3560 works. It happens almost instantly. I can't figure out why connections are dropping. The APs have about 4 VLANs onn them, and the PCs are on their own VLAN (the native VLAN).
