I want to expand my network with this switch. I have a cable from a DSL router directly connected with a network device. Now I want to connect first from my DSL router with the switch and then from the switch to the network device. But which port of the switch to connect with the router?

The cisco that is being devlivere is coming with a 48 port switch and 24 port fibre switch. Could I change any of those ports into a router port and configure IP addresses on those?

I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.
I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.
View 2 Replies View RelatedIm not going to lie, I'm pretty much a beginner when it comes to switches. I have recently purchased a second hand 3512 XL which I have managed to connect to via PuTTY and the console cable. I have familiarized myself with access privileges and resetting passwords and locating the IP address, etc.
I am trying to connect the switch to Cisco Network Assistant however I am unable to connect to the switch over a cat5 on the first port (nothing else is on the network, just a server directly to the switch). I have tried pinging the switch from my server, and similarly I have tried pinging the server from the switch and each time there is 100% fail rate.
Why I cannot ping vlan when no port connect to switch.
View 3 Replies View RelatedI have a Cisco 1941 K9 Router. I want to add POE functionaltiy to it. Specifically I want a 4 port EHWIC POE switch to power a couple of AP's.
This is what I understand I need; Upgrade/replace the internal power supply with PWR-1941-POE power supply, This is supplied with a fan replacement also (not yet purchased).buy 1 x EHWIC-4ESG (4 port switch)buy 1 x ILPM-4 (inline daughter card / power supply board) I think the real question here is the 4 port switch... there are two types available one is EHWIC-4ESG=the other is EHWIC-4ESG-P=
Is there any difference between these two switch modules? or are they the same and the more expensive "P" version is simply supplied with the ILPM-4 daughter card for POE?
I have recieved via courier today 1 x EHWIC-4ESG, and found a ILPM-4 on ebay for a good price. WIll this provide POE through the switch EHWIC-4ESG?
My questions is can a 4 port PoE switch module (EHWIC-4ESG-P) and a 8 port switch module (EHWIC-D-8ESG) be used at the same time in a Cisco 1941 router?

I have a small lab setup and I am trying to implement an IDS/IPS on the network. I have 3 VLANs setup (10, 20, and 30) with the switch and a router allowing for inter-vlan communication. Port FA 0/1 on the switch is setup as a trunk using 802.1Q connected to a single interface on the router.
I want to be able to monitor traffic on the trunk link on the switch and replicate that to the IDS/IPS host. Is there a way I can mirror traffic from FA 0/1 (the trunk link) to a regular access port on the switch which would connect to the IDS/IPS?
I have seen several articles on Cisco.com saying that you can have a source port as a multi-vlan link, but others say it is not possible. I did not have a chance to get into the lab to test this yet or else I would have.
I implemented the 3560E switch, this one have two Giga bit ethernet/10-Gigabit Ethernet module slots. I used the Twin Gig Converter Modules and one SFP. All configuration was applied in the Ten Giga bit, however the interface giga bit ethernet is UP UP state and the Ten giga down down.

This output fires several times a second, and based on how often it is firing, I am curious if it may be a culprit with respect to the fact that the client has indicated that they have some slow internet.Should the next step be to look at the workstation at 172.16.1.5?

View 1 Replies View RelatedI have 2 Catalyst 2924 switch in a home lab. Both of them have developed the same problem at the same time (strange). I have tried all that I can think of. I can telnet to them but cannot access via the console port. On a telnet session I execueted a "write erase, reload" on one of them. As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
The console cable is fine, works for all other devices.
I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.
