HWIC-2FE V01 not detected on Cisco 2800 router

I have a Cisco 2811 router. The IOS is C2800-NM-AdvancedEnterpriseK9-M ver 12.4(22)YB8. I shut the router down and installed an HWIC-1T ethernet port card and restarted the router. The router does not recognize the HWIC, no additional interfaces show up in the config. When the router restarts, the LEDs adjacent to the two ehternet ports on the HWIC light up and stay green even when nothing is plugged into the ports.

I read the data sheet for the hwic and it says that you need as a minimum 12.4(20)T or better for the software release and IP BASE as the software package.

What else do I need to do to get the Cisco 2811 to recognize the card?

Your current YB version may be older than the requested 12.4(20)T so I would also recommend loading this version (or the latest 12.4T version) and seeing if your card gets recognized.


In addition, could you perhaps post the WS-X45-SUP7L-E  output of the show diag output?

How to connecting 2 cisco 3560 switches

I try to connect 2 WS-C3560X-48T-L   switches with the 1000base-t sfp's. Tried a normal and twisted UTP cable, both no result.

Tried hard coding speed and duplex,
The connection is available at 10 and 100mb with full duplex.
Tried to connect at 1000mb it fails, i think that it is the specs of the cable (utp5 shielded) that is the problem.

digging at the cisco site i finally found some info about the specs of copper cables, but it isn't very clear.

going to buy a cat 5e/6 cable and try it again.

said by DaSneaky1D:

Have you tried using a cross-over cable?
GigE doesn't care about patch or crossover. it uses all four pairs so all you need is the pairs "paired" correctly.

said by cow116:

for 10/100/1000bps ethernet you need cat 6/6e(if they make it) for gigabit. cat 5e is only good for 10/100 and maybe 1000 if u get lucky


Cat5e is fine for GigE, no current standard requires Cat6. by far the most important thing is connectors, some people pull to many twists out when making custom cables. this is a big problem for GigE as FEXT and NEXT can happen very easily. if you're sloppy and pull the twists out you'll have "strange" issues.

said by davelaw:

gig over copper cabling from switch to switch requires a special crossover cable that can be found on the cisco website. Gige uses 4 pairs, many xover cables only cross pairs 1,2 to 3,6, but all 4 pairs need crossing for gige.
see answer 1

what model switch do you have? a 3560-24PS or WS-C3560X-48T-S , all the fastE ports are 10/100. only the SFP ports are GigE. it sounds like your trying to set the speed on the wrong port in the config.

B-ACD with Non CME 2900 series H232 Gateway

I got a request to block non-notice (calls with blank calling numbers) calls with voice prompt. The calls are comming from BRI configured in a Cisco 2921 price  H323 gateway.

For this I am thinking of putting BACD application with a welcome prompt for the caller and drop through after that to a random number to end the call. This is only the requirtement and not planing to use the ACD feature of the script.

Can I do this with a h232 gateway 2921 that is not CME (only CME-SRST)? is there any other better way to do this. In normal mode calls are going to CUCM 6.1 using voip dialpeers. Callmanager related configurations are not shown here.

Configuration:

------------------------------------------------------------------------------------------------------------ Identifying blank calls

ip source address <loopback>
max-dn 2
max-ephone 2

Though you could do it with BACD & a drop through, I wouldn't do it like that.  A cleaner solution is to throw the call to your AA (Unity, CUE, IPCC).

voice translation-rule 1
rule 1 /.*/ /8675309/

voice translation-profile block
translate called 1

dial-peer voice 1 pots
answer-address ^$
translation-profile incoming block
direct-inward-dial
port 0/0/0:23

dial-peer voice 2 voip
destination-pattern 8675309
Add other h323 peer stuff here....

What this does is match peer 1 inbound for any inbound POTS call that doesn't contain an ANI.  It then takes that call and translates the DNIS to a special pattern, and sends it to CUCM.  Then configure CUCM/Unity/whatever to router 8675309 to an AA that say 'Hey your call is being blocked because you aren't presenting CLID'
Cisco 2951 price 
 and hang up.

cisco 3750 - stacking and vlans

I have two WS-C3750X-12S-S    switches stacked.

I created a vlan giving

 vlan 10

name test

 then i gave the vlan 10 an interface ip address.

 "interface vlan 10

ip add 10.20.4.1 255.255.255.0"

 BUT the problem is I cant ping this inteface even being inside the switch.

There is an ip for the vlan 1 and i can ping that ip.

 "sh vlan brif" - shows vlan 10 is active

I tried "no shutdown" in the vlan interface. No result

 ip routing is also enabled.

 I have been doing intervlan routing with 3750. but this is the first time with 2 switches stacked. Is stacking to do anyting with vlans.

Check the output of show interface vlan 10.

 I am sure it won't be UP and UP.

 The reason might be because there is no switch port elonging to VLAN 10 as pointed in the above post.

Connect a PC on an interface. Configure that interface for VLAN 10. Wait untill the physical interface comes up and then again check the output of show interface vlan 10. Now it should be up and up  and you should be able to ping it from the swithc and other devices as well as long as they have IP connectivity.


Conclusion - there should be an interface assigned to that VLAN and that particular physical interface should be up. Only then the WS-C3750V2-48PS-S    VLAN interface would come up.

Catalyst 3750 Smartport Roles

I have 4 stacks of Catalyst WS-C3750X-48T-L   switches for my LAN infrastructure, and they're all configured with multiple VLANs, QoS, etc. in conjunction with a Unified Communications system. On most of my client ports, I've applied the IP Phone+Desktop smartport roles, and likewise AP/Switch/Router roles for those devices.

My question is this-- is it appropriate to apply a smartport role on the switch ports connected to ASA devices (ie. can an ASA be treated as a switch or router)? If not, in addition to trunking, what other parameters should applied to those ports to optimally configure them?

You can treat the ASA as a router to all intents and purposes. Although you talk about trunking, are you trunking yout switch to the firewall ?

Okay, personally i would just configure it manually because it makes sense to only allow the vlans you need on the trunk link ie.

int gi0/1  <-- this connects to ASA

switchport mode trunk

switchport trunk encapsulation dot1q


switchport trunk allowed vlan WS-C3750X-24T-S   <vlans that are going to ASA>

ZD3000 and Cisco 3750 Trunk port with native vlan question

I have typical network topology ISPROUTERL3_SWITCHL2_SWITCHES
L3_SWITCH = WS-C3750X-12S-S   does Inter-vlan routing.
My Ruckus ZD3000 is directly connected to L3_SWITCH
ZF Access Points are connected to L2_SWITCHES = WS-C2960S-48FPS-L

Lets say i have 3 VLANs:

254 - IT_MANAGEMENT
10 - WIRELESS_GUEST
11 - WIRELESS_STAFF

I would like to configure port as trunk with allowed vlan 10,11 and native vlan 254 on L3_SWITCHZD3000

trunk with allowed vlan 10,11 and native vlan 254 on L2_SWITCHESZF AP`s

The idea is to manage ZF`s via ZD3000 trough vlan 254 and send regular "user" traffic over vlans 10 and 11.

As of right now when i do trunk with allowed vlan 10,11 and native vlan 254 on L3_SWITCHZD3000 - i and not getting any connection to ZD3000. only if cisco`s port is in access "mode".

I think you are not able to access the ZD WebUI from your laptop is what you mean when you say "not getting any connection to ZD 3000". Am I correct? Also, I believe that APs are able to connect to the ZD..right?


Can you confirm that the native VLAN on each port that is connected to the AP's and the ZD is the management VLAN and also that WS-C3750V2-48PS-S  each port has trunk enabled?

cisco 3560 router or switch!

Opmanager 7 (fresh install, latest version, plenty of server power) has decided to randomly categorise my cisco WS-C3560X-48T-L   series switches as either 'router' or 'switch' depending on its mood.
The ones classed as router come up as 'cisco device' even though in the description field below that box it says 'cisco 3560...blah blah'.
If i then go and change the device type to 'cisco 3560 series switch' i either get page that says 'error' or 'device cannot be found'.. if its the latter its been deleted from the database and i can't re-add it as its partially there....
we will match the sysoid on the device template and based on it, the device type will be applied. So if there are no templates for the device it might be associated wrongly. So to make the cisco 3560 device fall under the right category, create a new template by following the steps in this LINK. Now you can apply the template to all the 3650 devices and it should work fine.
For the device being partially added, follow the steps in this LINK which will remove the device completely from the database. Now add the device again and it should be fine. We will make this template available out of box soon.

If you have the device template already, then you don't have to create one. You can go to the particular template under Admin --> Device templates and apply it to all the cisco 3560 devices. While discovery, if you have multiple credentials selected or if the response for the SNMP request from the device is slow, then it might get timed out and fall under the general cisco  WS-C3560X-48T-S   device category. Applying the right template all the devices will move to the correct category.
