Cisco Switching/Routing :: 1941 Port-Security With Router Switch Module

Feb 29, 2012

I have a 1941 that I am going to deploy with a HWIC-D-9ESW switch module (I only need 3 switch ports but need the PoE).  I am going to hang a 1262 autonomous AP off one of the ports but I need to configure MAC address port-security so that only that AP can pass traffic. I know the switch modules are 'almost' exactly like a switch for commands but I can't seem to enable or configure any port-security settings.  Is port-security no available on the switch modules?

Cisco Switching/Routing :: Configuring 1941 With 8 Port EHWic Switch Module And Onboard GE Ports In Single LAN?

Jul 1, 2012

Can you configure a Cisco 1941 to use an 8 port EHWic module and the 2 onboard GE ports in a single LAN?

I've discovered you can't have the on GE ports associated with a VLan, and I'm when I've previously researched for a solution, bridging was mentioned but I cannot seem to get it to work (or completely understand it)The reason I would like to use all 10 ports on for the LAN is becuase I have 10 devices I need to connect to the 1941?

Cisco Switching/Routing :: Convert 1941 Router To POE With 4 Port Switch

Dec 20, 2011

I 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?

Cisco Switching/Routing :: 1941 Upgrade With 4 Port POE Switch Requirements?

Dec 5, 2011

I have a cisco 1941 router.  Stock standard vanilla hardware, no extras.  Standard universal image.  Data and Security not enabled.I would like to add a 4 gigabit port POE switch (EHWIC) module to the router..The 4 port POE switch module will be used to power and connect 2 x Areonet AP's for my home.  I'm replacing a Apple Airport Extreeme and Express setup.  I'll possibly later use the two remaining POE ports for security cameras.My question is, what extra hardware and or IOS version do I need for the POE swtich module to function on the 1941?  [URL] I think this is the model I want EHWIC-4ESG-P #4 port 10/100/1000 Enhanced High-Speed WAN Interface Gigabit Ethernet switch with Power over Ethernet?

Cisco Switching/Routing :: 2811 With 16 Port Switch Module Configuration?

May 12, 2013

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.

Cisco Switching/Routing :: 3925 With 48 Port Switch Module Infinite Loop

Jan 19, 2012

I have a 3925 Router with a 48 port switch module (part number SM-D-ES3G-48-P).  I have no problem accessing the 3925 Router, but when I go into the 48 port, I get an error that reads
Error Hardware not supported by firmware. Try loading a newer software instead. System Resetting...
I know that the wrong IOS is installed on the switch, but the problem is that this is an endless loop.  The switch resets then comes back to the same error.  How to get the switch out of this loop so that I can load the correct IOS.

Cisco Switching/Routing :: 1941 Router GE0/1 Port Burnt And Need To Configure

Aug 29, 2012

I Have a Cisco 1941 router which had its GE0/1 port burnt out and we have since plugged in a module with 4 fast ethernet ports. I need to reconfigure the router such that at least one of the Fast ethernet ports can server the purpose of the GE0/1. GE0/0 connects to our Service provider and GE0/1 connected to the inside network.Currently, while connected to one of the ethernet ports, i can telnet into the router on the address when i'm on the router, i can ping our remote site, network address with no problem, but when i use the command "Ping source" there is no response.

Cisco Switching/Routing :: How Switch Module Works In 2911 Router

Sep 4, 2012

how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.

any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.

Cisco Switching/Routing :: Convert Switch Port To Router Port On 6500

May 8, 2012

On the supervisor card of a cisco 6500 series, according to the following link, [URL] it only has 2 uplink ports on the card. Would I be correct in assuming that I only have those to ports that I can configure IP addresses on?
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?
The supervisor card is a ws-sup-720-3b the 48 port switch is a ws-x6748-ge-tx the 24 port fibre switch is ws-x6724-sfp

Cisco Switching/Routing :: 3825 ISR - Traffic Route From Switch Port To Router Port

Jun 5, 2013

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.

Cisco Switching/Routing :: Additional RJ45 Port Required On 1941 ISR

Nov 16, 2012

One of branch locations has a Cisco 1941 Router . The port details are as follows
-Gi0/0 - ISP line
-Gi0/1 - Inside Network ( To a 2960 Switch)
Now they have procurred another line from ISP through which  MPLS based VPN to the Main location is configured. What are the options I have , to terminate it on the Router ? As all the On board LAN ports are filled I guess I wont be able to do anything with the current setup .Are Switching modules available ? What is the Embedded-Service-Engine0/0 port that I see on #sh ip int b output ?

Cisco Switching/Routing :: 1941 - Use One Ethernet Port (G0/0) As Primary And Other (G0/1) As Backup Interface

Jan 20, 2013

Here's my problem.  I'm going to be using Cisco 1941 routers at a bunch of remote sites.  All of these sites have 2 comm paths out.  Some of them have 2 IP/VHF radios and some have 1 IP/VHF radio and a copper link using Patton ethernet extenders.  From the VHF radios the data hit our MPLS network back to our HQ and the sites with copper go directly back to our HQ.  Everything ends up at a Cisco 4948 switch. The problem I'm having is that I want the routers at the remote site to use one ethernet port (G0/0) as the primary and the other (G0/1) as the backup interface.  I've tried the backup interface command but the problem is that depending on where an outage occurs the ethernet link to either the radio or Patton stays up so it never switches over. We're using OSPF as our routing protocol and I'm sure there's something that can be done with it but I'm not sure what.

Cisco Switching/Routing :: Setting Up Switch Module On 2951?

Sep 18, 2012

I'm trying to set up a 2951 with a 24 port switch module. I want the ports to act similiarly to the ports on an 881 router - where I assign the VLANs on the router and I set the VLANs to the switchport interfaces.I would like to be able to create the VLANs on the router portion of the 2951 and then, enter the switch module and configure the Ports to the VLANs but, how do I logically connect router to the switch? Is it an internal logical interface - meaning how are the VLANs getting from the router to the switch?

We having a VSS switch (9 slot chasis) with ios "s72033_rp-ADVENTERPRISEK9_WAN-M), Version 12.2(33)SXI4", slot 7-9 are currently free. We wanted to install WS-X6708-10G-3C module on slot 7. Once we installed the module it didnt come, after waiting for 15-20min again we removed and inserted, but module didnt come up and we could see following logs on the console:
Jan 12 08:57:40.146: %ISSU-SW2_CFC2-3-ERP_AGENT_SEND_MSG: client/entity send failed; error code is timeout

Afer some time VSS switch didnt response to console commands and all the users in access switches were not able to reach the gateway (VSS). Then the problem disappeared once we rebooted both the switches in VSS.why the VSS switch become non-responsive?

Cisco Switching/Routing :: 4500 24-port Gigabit Module Being Picky

Jan 7, 2013

We have recently purchased a Cisco 4506 that has several Gigabit Ethernet modules installed.One of the Ethernet Gigabit modules - a WS-X4424-GB-RJ45 - is being picky with who it talks to at Gigabit Ethernet.
If I plug a laptop into one of it's RJ45 ports using a Cat 6 cable, nothing happens.  No link light, no notification of link up or down on port statistics, absolutely nothing.If I plug a server into the same port it works fine at Gigabit Ethernet (even using the same Cat 6 cable).I can get the module to recognize a laptop if I fix the speed/duplex on the laptop to 100Mb/Full. I have tried this with other staff laptops from different vendors (HP / Dell / etc.) all with the same result.
The module directly underneath this module - a WS-X4448-GB-RJ45 - works fine for both laptops and servers.  We have tried swapping the module positions but to no avail.

Cisco Switching/Routing :: Enabling Port Security On C4507R Shuts Down Port
