Cisco Switching/Routing :: Can RPS2300 Support 2960S

Aug 18, 2012

When using dynamic configuration tools, if I choose 2960 (not 2960s), I have the option to choose RPS2300 as redundant power, but when I choose 2960s, I cannot choose RPS2300. However, in a document describe both 2960 and 2960s, it said that RPS2300 can be used. Does RPS2300 support 2960S?

I know the white papers say that the RPS 2300 supports the 3750-E series and the 3750 series, but we have 3750-G and -X series.  Wanted to make sure that these switches are supported and if we need anything special?

Cisco Switching/Routing :: 2921 Process Of Switching Infrastructure Of Firewalls / VPNs

Jul 4, 2012

We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco.  We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages.  Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication.  In the past, because they are logged into the domain internally, the website authenticates and loads.  After switching to the Cisco, it asks for a password even though they are logged in.
 
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

Cisco Switching/Routing :: 2921 - VTP Design

Jun 22, 2012

We have remote office where we have 2921 router with 6 layer 2 switches. We have few servers which need to be in specific vlan.
 
2921 router does not have switching engine we are using this to support VOIP.

So on 2921 router i created 6 sub interfaces for each vlan and assign them to their specfic vlans. Then I have trunk connection to switch 1. Now switch 1 connects to all other switches in the network. As our company design all layer 2 switches should be transparent mode. i tested them i can ping from one switch to all other switches.

Router vtp mode i set to transparent mode and from all switches i can ping the router sub interfaces.

Cisco Switching/Routing :: 2921 Interface Not Coming Up

Oct 2, 2012

I have a CISCO2921. I am not able to bring up its gi0/1 interface. It stays down down.
 
[URL]
 
I know that interface is not coming up because of "no media" below. Router#sh int gi0/1 | i media  Auto Duplex, Auto Speed, media type is no media
 
I have tried media rj-45 and media sfp which have also not worked. The other end of this link is ethernet handoff. What is it that I have to do for the link to come up? If I change the connection to gi0/2, I think that will work because I see this for gi0/2:
 
Router#sh int gi0/2 | i media  Auto Duplex, Auto Speed, media type is RJ45

Cisco Switching/Routing :: 2921 Connecting To Non Managed Switch

Mar 21, 2012

This is for a short temporary time until I get cisco 3560s in place. I have a 2921 configured  and it is connecting to an HP non managed non VLAN switch and I cant get any traffic to pass from my computer to the router (pings or anything). Here is brief configuration that should be enough. [code]
 
Here are my vlans 1-default, 2-management, 192-data, 92-voice, i believe its running rapid spanning tree protocol. Do i have to take off encapsulation on my data vlan to get it to work or make the data vlan default vlan for everything. I am lost as to why this is not working.

Cisco Switching/Routing :: 2921 Multiple Netflows From Same Router

Nov 15, 2012

What I’m looking to do is setup a net-flow monitor for traffic going across a PIX firewall. I know unfortunately I can’t do this directly from the PIX because it does not support net-flow.
 
I do have a 2921 router on the same network that I have net-flow enabled to monitor traffic across the MPLS Connection.
 
Since the traffic for the MPLS is going out a direct interface I have applied the IP Flow egress/ingress commands to that interface to obtain the net-flow data I need.  The PIX firewall however is not a direct interface so this can’t be done. I have done a little reading and believe I could use a policy map to create a “filter” so that any traffic that meets the ACL associated with the Policy-Map would get sent to net-flow monitor.
 
My question is how do I set that up so that so I can have the two net-flow data “streams/sources” go to separate net-flow ports so that I can monitor them independently of each other or is that not possible?
 
Both devices are connected to a 3750X switch; however neither is connected to a 10GB port. To my understanding that means I can’t run net-flow on the switch itself.

Cisco Switching/Routing :: 2921 - Queue-limit With Shaping

Mar 8, 2012

I have a 2921 where I am shaping some traffic based on sub net on my lan.  I have applied the shaping policy to the lan interface in the outgoing direction.
 
Topology is as follows:  
ISP - ASA - ROUTER - LAN 
Policy map: 
Policy Map shape-lan
[code].... 
 
I am seeing a lot of no-buffer drops on the policy and I am wondering what the best solution is to solve this: 
Class-map: tc-class (match-any)
   8730680 packets, 10803689863 bytes
   5 minute offered rate 4453000 bps, drop rate 0 bps
  [code]....
 
Should I just be increasing the queue-limit or should I be changing something else?

Cisco Switching/Routing :: To Configure Multiple LAN Ports On Router With Same 2921

I have 2921 router and I have 3 very basic switches that I need to connect to the router. The switches have very basic default configurations and there is no way to edit them, so I only have one VLAN and one default gateway. I can't assign the same IP address to each LAN port. I'm not sure how to make this setup work.

Cisco Switching/Routing :: 2921 - Network Segmentation And Internet Bandwidth Splitting

Feb 24, 2012

Now I have a 172.16.0.0/16 network with a def. gw. for internet where is a MS Forefront TMG 2010 with BSplitter for traffic shaping. I purchased an 2921, 2,5 GB RAM, security+data license and an EHWIC-D-8ESG.

I made 4 subnets in a test environment with some access-lists, nothing fancy yet. How can I use FF TMG for bandwidth management, where should I put it? For those 4 subnets the def. gw. is, normally, the 2921 router. TMG is splitting traffic by client IP.
