Jan 12, 2013
i have a router 2921 with the aproprieted voice card for E1 and licenses. I would like to know how to configure it for incoming and outgoing calls. I already configured the ephone and SIP phones for internal calls. now i just need to configure it for send and receive external calls.
Router:
IOS: c2900-universalk9-mz.SPA.153-1.T
CME: 9.1
ISP from Brazil:
type: E1
signal: R2 Digital
Channels: 32
Phone Number Iniital: XXXX-9250 (main)
ephones-dn numbers: 9250 to 9280

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.

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.

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

configuring up a 2921 router for remote site which is fitted with 24 port Etherswitch module.As part of this setup I have defined 3 vlans on the router, but when I go onto etherswitch and for example set switchport access to access vlan 3 it is not aware of this vlan.Do I have to set up trunk inbetween Router and its etherswitch?Wish I had ordered seperate switch as it would have been easier or am I missing something.sho vlan-switch shows my vlans but on swicth sho vlan brief does not.

An interface on 2921 router is not coming up. When I shut/no shut the interface, I see this:

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.

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.

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?

I can not find any information about management port of Cisco ISR 2911, 2921 and so on. There is management port in specification of 2911 and 2921 and I do not know if this port can be as a simple Ethernet port – forward traffic in/out on L3.

the cisco 2921 Router has a default ip hhtp access class command found in it. Just i changed the default IP to the new ip i will use.The Router is accessable from the LAN only but not from the internet configured the Public ip . I think this is due to the standard access list 23 . how will i access the Router from the Internet using the Public IP.

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.

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.

We recently purchased a Cisco 2921 router to be our edge device for a small satellite office (24 users). In addition, to the router we purchased a vwic3-2mft-t1/e1 module. Now the surprise, we ordered a bonded T1, I thought we were getting frame-relay circuits from Verizon, but someone ordered a 3M IMA circuit. I am new to configuring serial connections, and had planned out a frame-relay configuration. With that said, I have the following questions:
1. Can I setup a working serial connection to Verizon using the installed ATM circuit and the 2921 and vwic3-2mft-t1/e1 card I have? If not, what do I need in conjunction with the 2921?
2. With the frame-relay configuration, I enable controllers, configured the MFR interface and sub-interface, and serials. How much different is setting up serial ATM connections?

I've one Cisco 3750G-12S with ip routing enable, the swtich is with IP Service firmware, with PRR support.Currently set my default static route 0.0.0.0 0.0.0.0 10.1.18.71 to my Firewall A Currently all of the VLAN for will be routed to 10.1.18.71
I've created a new VLAN 2 for my 10.1.2.0/24 network with the VLAN interface 2 ip address 10.1.2.10, my intention is to route 10.1.2.0/24 traffic to my 10.1.2.1 by creating the access list and route-map.
I've configure my test pc with a static ip and my gateway pointing to 10.1.2.10 (VLAN 2 gateway) , i'm not able to route to 10.1.2.1.
