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 :: 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 :: Can Port Channel In 3825 Connect To Two Different Switches

Jan 17, 2012

We have one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.

Cisco WAN :: 1700 - Route RDP Port Based Traffic To WAN Interface

Jun 11, 2013

this is my first time configuring a cisco router. For instance, a cisco router 1700 with 2 ethernet WICs and 1 LAN port. We have 2 ISPs one more stable than the other. We use an RDP session to an external host identified by lets say IP address 200.1.1.2 using ISP2 to get to this computer.   We use ISP1 for all the internet usage, web pages, youtube etc.  We are thinking of using this cisco router 1700 to make the packet filtering and routing of this RDP session to the correct ISP2 since we only have 1 NIC per computer on the LAN side.
 
The main idea would be:
 
                                                       | YES -----> ----------- then use  ISP2
LAN--------->  Are the packets RDP ?
                                                       | No-------->  ----------- then use ISP1
 
Does this can be achieved using packet filtering using extended ACLs and to be router from the lan interface to route rdp (port 3389) packets to ISP2 WAN interface?

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 :: VTP Traffic Not Seen On SPAN Port On 3750

Dec 12, 2011

Been dealing with a strange problem for several days now.  It started out with a problem that I thought was VTP related but ended up being something else.  I setup a span port on a 3750 that I am connected to that was mirroring the trunk connection coming into the switch.
 
Never saw an VTP traffic come across the connection but doing a sh vtp status indicated the traffic was arriving and getting processed.  When I found some debug commands (debug sw-lan vtp), I was also able to see the packets go between switches.  Seeing this issue concerns me that there is other traffic that isnt showing up during a span session.
 
I know that doing a span on a switch, especially using a trunk port as a source, isnt a good idea.  Since I didnt have a TAP at time, this was my only choice.  I have since borrowed a NetOptics TP-CU3 tap from a good friend and was able to confirm the VTP traffic was going across the trunk connection between switches.
 
All of my 3750's are running 12.2.55.SE.

Cisco Switching/Routing :: ASA 5505 Dropping Port 443 Traffic?

May 10, 2012

Networking is not my gig, but it has to be at this very moment.  We have an ASA 5505. Let me explain what's going on.
  
On Tuesday I wanted to be able to use the ASDM since there is less room for error.  But we only had a console set up.  So I ran the following commands...
 
in ($config)   
http      of course didn't do anything incomplete command
http 192.168.1.2 255.255.255.255        didn't anything incomplete command
http 192.168.200.254 255.255.255.255 inside 

[Code]....

Everything started working after that.  Everything worked fine all of wednesday and thursday.  Then this morning it stopped processing again.  When I traceroute it gets to the machine that is hooked up to the console and stops.  So I'm guessing its actually getting to the ASA router and being swallowed up again...

Cisco Switching/Routing :: 3750 - How To Isolate Fiber Port Traffic

Jun 18, 2012

We would like to setup a link to our DR site that is separate from our main network traffic.  This link will be used by an EMC VNX SAN for replication traffic.  The SAN will be plugged into a fiber port on a 3750 switch and going out from the same switch (going in as multimode, going out as single mode) into a patch panel that runs over to the DR site (about a mile away).  At the DR site it will go from the fiber panel into another 3750 switch which ends up going back out of that switch into our DR SAN.
 
I'm wondering what the best way would be to configure the fiber ports to accomplish this.  I'm affraid that the replication traffic will find it's way over through another route and congest our main network unless configured appropriately.

Cisco Switching/Routing :: Unexpected Traffic On Nexus 5000 Trunk Port?

Feb 6, 2013

So I took a laptop with wireshark and plugged it into a nexus 5000 port that is configured as a trunk with 3 vlans allowed on it. The laptop was seeing all kinds of traffic on the wire, most of it was not involving my laptop.
 
For example: Server A VLAN 10= 10.10.10.1  Server B VLAN 20= 10.20.20.1 and wireshark laptop is plugged into a trunk port which is allowing those vlan's. The vlan's are routable.
 
10.10.10.3 is seeing the entire conversation when 10.10.10.1 backs up 10.20.20.1 even though it has no reason to see it. It is as if the trunk is spanning traffic to the laptop port. No span is setup however. It's really weird. This is not just broadcast traffic, but actual tcp taffic between Server A and B. Why would a trunk port see traffic between 2 other servers talking to each other on the vlan.
 
Trunk port configuration below:
 
Interface Ethernet 141/1/3 
switchport mode trunk
switchport trunk allowed vlan 10, 20

Cisco Switching/Routing :: How To Setup Traffic Shaping On 4500X Outbound Port To WAN Routers

Mar 26, 2013

We have some ASR WAN routers which have a dedicated 400M interface to a remote site.
 
Servers on our Local network source the data through some firewalls via 10G interfaces, which connects to 4500X WAN switches then to the Routers on 1G links.
 
The sources are rate limiting the traffic but the routers are periodically dropping packets which I think is mostly due to burstiness in the traffic between as it traverses through from 10G links to 1G then to 400M. 
 
How to setup traffic shaping on the 4500X outbound port to our WAN routers.I'd like to see if we could buffer and smoothe out the traffic as it exits the 4500X WAN switch 1G port to the WAN Routers.
