We recently purchased the Cisco Router 2951 router with the IOS 15.0. I have tried to put in my VIC2-4FXO card in it. When I did show invetery, it detected the card.[code] When I tried to configure the voice port by typing voice port, it shows % Invalid input detected at '^' marker. I have tried to reset the cad and replace with another one.

Cisco Switching/Routing :: 3560 - What Happens When Voice Vlan Command Is Added To Trunk Port

Oct 11, 2010

Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
 
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.

Cisco WAN :: 3845 - Correct To State That VWIC2-2MFT-T1/E1 Can Support Data In Addition To Voice

May 10, 2013

I have a 3845 edge router connected to the Internet via four T1s and a HWIC-4T1/E1 card. We are adding two more T1s to the mix, and I have a VWIC2-2MFT-T1/E1 card. Here are my questions:
 
1. Is it correct to state that the VWIC2-2MFT-T1/E1 can support data in addition to voice?

2. I can use the HWIC and VWIC cards together to utilize the 6 T1s together?

3. Do I just add the card, configure the new slot, and add it to the same channel group?
 
Below is the current config regarding the existing card HWIC:
 
card type t1 0 0
security authentication failure rate 3 log
security passwords min-length 6
logging message-counter syslog
logging buffered 51200

Cisco :: Switchport Voice Vlan Command Not Putting Port In VLAN?

Feb 2, 2011

I have set up 2 DHCP pools and 2 VLANs (1 *the native* for data / 1 VLAN for voice). When I use the command "switchport voice vlan 20" the port disapear from the show vlan brief list. When I use the "switchport access vlan 20" it shows up in the show vlan brief in the correct VLAN and gives the phone an IP. I assume that using the access instead of the voice is wrong and the phones would not configure correctly. But when I use the access the phone goes to the next step and tells me the TFTP files are not found. Why does the port disapear from the VLAN list?

Cisco :: Rate Limiting On 3825?

Feb 24, 2011

I have a 3825 with a 16 port etherswitch card installed that I'm trying to setup rate-limits on. Interface G0/0 is the connection to the outside world and int g0/1 has a couple of 2950 switches attached to it.

The etherswitch card, f1/0, f1,1 etc has corresponding vlans, 902, 903 etc each with an IP 10.110.1.x, 10.110.2.x and all part of access-group 111. The switches connect on sub-interfaces g0/1.101, g0/1.102 etc and have IP's 10.55.1.x, 10.55.2.x and part of access-group 101.

What i'm trying to achieve is that every port / IP that is on access-group 111 shares 3Mb of bandwidth in/out and access-group 101 shares a separate 3Mb of bandwidth in/out.

I've created two access-lists as follows;

access-list 101 permit ip 10.55.0.0 0.0.255.255 any
access-list 111 permit ip 10.110.0.0 0.0.255.255 any

And on int g0/0 I've created the following rate-limits;

rate-limit input access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit input access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop

Now instead of both access-groups having 3Mb each they all seem to be sharing 3Mb! I've tried class-maps and policy-maps but to no avail..

Cisco WAN :: 3825 - Slow CIFS Over WAN

Jul 4, 2012

This is a multi site network. Site A has a Cisco 3825 router and connects to 3 other sites over ISP A and 2 other sites over ISP B. Both ISP A & B provide a layer 2 full mesh network. ISP A provides a 100mb pipe while ISP B provides a 20mb pipe.
 
File transfers (Windows - CIFS) over ISP A's fiber are fast enough and throughput is good. However, file transfers (Windows - CIFS) over ISP B's fiber are slow, even though latency is good. On the 100MB ISP A pipe, file transfer speeds up to 6 M Bps are achieved. On the ISP B 20MB pipe, speeds up to 300KBps are seen for file transfers.
 
ISP A connects to an on board gig port on the 3825. ISP B connects to a fast ethernet port on an HWIC-2FE card on the same 3825. Both ports then connect to ISP Switches and then full meshed to remote site Cisco routers. What could be the issue? Why am I facing these issues only with ISP B even though the configs for ISP A and ISP B are the same?

Cisco WAN :: NAT And Memory To Tackle With 3825

Dec 16, 2011

we have some unusual  issue when our core 3825 series router dealing  with NAT !first off to offload traffic we have two router one 3825 and other 2821 configured to support GLBP .

interface GigabitEthernet0/0
ip address a.b.c.d 255.255.255.0
ip nat outside
ip virtual-reassembly
[Code]....
 
The problem is router hangs out , intenet users suffer slowness , criticle service like telnet doesnt work . the only solution i found is a reload ,not to mention this is core router sitting on campus network edge . and servicing around 1000 users !! approx assuming all users have using internet at same time .
 
how to check , if memory is not sufficient ?further if any users using utorrent or any thing like that , does it make enormous no of connections form same pc ?

is their any  licence requird for IOS IPS ?i prefer to turn this feature on to kill torrents connections ?  but i fear crashing  of router as no of users are huge !any know bug with glbp , nat with ip voice image  C3825-IPVOICE-M  VERSION 12.4(24) T4  ???

Cisco WAN :: 3825 Traffic Shaping And QoS On Multiple EVC

Feb 6, 2011

I have a 3825 with a 1Gb fiber card at one of my sites.  Our ISP and MPLS provider hand off a single gigabit fiber to us that contains 2 50MB EVC's.I need to apply QoS to one of the EVC's and shape them both to 50Mb to avoid upstream rate mismatch bottlenecks.  Both of the EVC's generally only push 10Mb during business hours.When I run UDP stream tests (various rates from 500k-6m that are marked as AF41) to one of my other sites I am consistently getting about 2% packet loss, despite the fact the circuit isn't even close to 50% saturation.  When I remove Shaping and QoS all together, the issue nearly clears itself up, except during peak hours and I get small bursts of packet loss, which is still unacceptable.When the pipe is at near zero utilization (after hours) there also is no packet loss with or with out the shaping/qos applied.

Cisco WAN :: Replace Our 3825 Screening Router

We use a 3825 router to screen alot of the junk from the internet side or our firewall. Its worked well for the last 4 years buthas rebooted multiple times in the last month for no apparent reason.At this point I think  I would prefer to replace it.Our current internet link is 100Mbps and this router handles that quite well. Is there an equivalent that I should replace it with, or should I just buy another 3825 ?One with an OOB management port would be nice.

Cisco :: 3825 - NMAIR WLC SSID Limitation?

Apr 17, 2011

I have a NMWLC6 module connected to a  3825 ISR using 1140N APs.  Latest (but one) code.  I had two SSIDs configured and deployed in the default AP group.  Last week I needed to deploy a third SSID for unencrypted webauth, I created the interface and WLAN associated with the interface and the sub interface/svi on the WLAN-controller 0/1 with dot1q.  All created with no problem and enabled, however the SSID was not available to clients and did not show up as available WLANs under AP groups menu. Out of desperation I created a new AP group and added an AP to it and hey presto all three WLANs were available and the third is now visible to clients! Is this normal behaviour? Is the default AP group limited to two SSIDs? (a quick google failed to find any documented limitation!) or is something weird going on?
