I need to contact him. He is spot on almost everywhere in the world except my neck of the woods. We have 2 other undersea cables that he needs to add Other than that is a most excellent source of info on the undersea cable systems.

Comment on Understanding and Configuring a HWIC-3G-GSM by Ruhann

What hardware version is your radio?
MTN requires v1.1.9.33, and suggests using either IOS 12.4(22)YB4 or 15.0(1)M. I personally would use 15.0(1)M.
(I personally have not tested MTN’s 3G with the 3G-GSM.

Another suggestion I might add to rule out hardware is to try a Vodacom sim. I used the Vodacom ‘unrestricted’ APN, but your testing for outbound/uptime should be fine on their ‘internet’ APN. (Note that a Vodacom sim must be activated (free) for their ‘unrestricted’ APN).
If the Vodacom sim works fine, I would suggest contacting MTN corporate and request their assistance connecting to their gateways with the 3G-GSM card.

Hth, else shout

Hi, I have a 3G-HWIC-GSM card in a 2811 router with the latest IOS. I am trying to set it up as a DDR link but even just trying to get it set up with MTN for testing purposes as a main link all that happens is the link goes up and down the whole time. When I use the simcard in a normal USB modem it works perfectly.

Not sure where to look anymore and any help will be appreciated.

Your modem should not disconnect without intervention.
It sounds like the keep alive signal might be incompatible between your modem firmware and your cellular provider.
Although the EEM srcipt is a nice quick hack, I would suggest you contact your cellular provider to enquire what hardware version they require for their equipement.
Keep in mind different Providers use different firmwares, and some dont support the Sierra Wireless MC8775 modem.
Refer to this link:
http://www.cisco.com/en/US/prod/routers/networking_solutions_products_genericcontent0900aecd80601f7e.html

Then I would suggest changing your firware to the compatible version.
Refer to this URL on the step

Our modem used to disconnect sometimes or was not willing to connect. Clear interface, clear dialer, shutdown methods would not help. In this case the modem must be reset or restarted (if you want to avoid a router reload)

(config)#service internal
(config)#exit
#test cellular 0/0/0 modem-reset

(config)#service internal
(config)#exit
#test cellular 0/0/0 modem-power-cycle
(this is better)

So why not automate the process? (-:

event manager applet 3G-reset
event syslog occurs 3 pattern “UNBIND: Interface Ce0/./0 unbound from profile Di0″ period 300
action 1.0 cli command “enable”
action 2.0 cli command “configure terminal”
action 3.0 cli command “service internal”
action 4.0 cli command “end”
action 5.0 cli command “test cellular 0/1/0 modem-power-cycle”
action 6.0 syslog msg “EEM Cellular modem power cycled”

The generalized AT command is:

ATD*gprs_sc*CID#

where gprs_sc can be
99 (GPRS Service Code) a digit string (value 99) that identifies a request to use the Packet Domain service.
98 (GPRS Service Code) a digit string (value 98) that identifies a request to use the IP service

CID (PDP Context Identifier) is the profile number (1..16). There can be multiple profiles in the modem. Apparently, 1 is the default and *1 can be omitted.

So ATD*99*1# or the simpler ATD*99# are the most common dial strings.

Comment on Out-of-Band network by Ruhann

Hey buddy

DSL would be cost effective, but requires a telco line to be installed in each DC. 3g is quick and nasty

SP been taking most my time.
I will start posting again soon.

Nice one dude.. I like the 3g option also. If you wanted to be a complete maniac you could use DSL 384k with prepaid. We talking cheap rates then also and slightly more reliable.

Been a while since you posted.. send us something awesome!

Comment on BGP Conditional Route Advertisement by Ruhann

Ruhann — Thu, 29 Apr 2010 12:06:46 +0000

The names used indicates its purpose
The ‘WATCH’ route-map is the route being watched
The ‘ADV’ route-map is the new route to advertise.

Good stuff, little bit difficult @ first. I think it will be more simple if word like BACKUP, PREFER where used when naming your route-maps.

Thanks for good work Ruhann.

To navigate to the ‘Configuration Guide’ or the popular ‘Master Index’ follow these steps.

For Routers:
Click on ‘Cisco IOS and NX-OS Software’
Then on ‘Cisco IOS’
Then on ‘Cisco IOS Software Release 12.4 Family’
Then on ‘Cisco IOS Software Releases 12.4 T or Mainline’
Lastly on ‘Configuration Guides’ or ‘Master Index’

For Switches:
Click on ‘Switches’
Then on ‘LAN Switches – Access’
Then on ‘Cisco Catalyst 3560 Series Switches’ or 3550
Lastly on ‘Configuration Guides’ or Command Reference’

Silly question, but how do you get to the Configuration Guides from http://www.cisco.com/cisco/web/psa/default.html?mode=prod ?
