Cellular configuration on a 4321

fmerkle

Hi Friends,

in the past we have used a C899G-LTE-GA-K9 , with a 15.5(3)M2 and a AME: "Modem 0 on Cellular0", DESCR: "Sierra Wireless MC7304 4G-GA"
PID: MC7304 . Now we switched to a ISR4431/K9 with a isr4400-universalk9.03.16.02.S.155-3.S2 and a "Modem 0 on Cellular0/1/0", DESCR: "Sierra Wireless MC7304 4G-GA" PID: MC7304 4G-GA.

Our C899 configuration seems to be invalid on the ISR. Is this a bug on the ISR ? We allready tried diffrent IOS Versions witout success.
The strikedthrough commands are not longer available.

Does anybody knows a workaround ?

interface Cellular0/1/0

encapsulation slip

no ip address

bandwidth 4000

ip address negotiated

ip virtual-reassembly In

dialer in-band

load-interval 30

dialer idle-timeout 0

dialer string lte

dialer-group 5

async mode interactive

no cdp enable

ip access-group 117 in

no shutdown

service-policy output OutputPolicy-Cellular0/1/0

Thanks

Frank

hi,

the dialer string lte is the default and the 'lte' is just an arbitrary name.

make sure the name is set the same on the dialer chat script line.

Router(config)#interface Cellular0
Router(config-if)#dialer string ?
  WORD  Dialer string (quote strings containing #)

Router(config)#line ?
  <0-25>   First Line number
  aux      Auxiliary line
  console  Primary terminal line
  tty      Terminal controller
  vty      Virtual terminal

Router(config)#line 3
Router(config-line)#script ?
  activation     chat script to run whenever line is activated
  arap-callback  chat script to run on line whenever ARAP callback is initiated
  callback       chat script to run on line whenever callback is initiated
  connection     chat script to run whenever connection is made to the line
  dialer         chat script to run whenever dialer makes an outgoing call
  reset          chat script to run whenever line is reset
  startup        chat script to run at system startup

Router(config-line)#script dialer ?
  WORD  chat script name

Hi Mate, I am having exact same problem, did you manage to get this fixed ? could you guide me?

We also struggeled here with ISR4k and LTE module especially when using in FVRF

!

vrf definition INTERNET
 !
 address-family ipv4
 exit-address-family

chat-script LTE "" "AT!CALL1" TIMEOUT 30 "OK"

!
interface Loopback0
 vrf forwarding INTERNET
 ip address 1.1.1.1 255.255.255.255 <-- needed as it needs any source ip (can be 1.2.3.4 as well)

!
interface Cellular0/1/0
 vrf forwarding INTERNET
 ip address negotiated
 dialer in-band
 dialer-group 1
 pulse-time 1

!

 

I am having the same issue with an ISR 4431 with 4G card.  One issue is i cant configure a 'line' statement. Say my interface is 'inferface cell0/1/0' when i try and enter 'line 0/1/0' its not accepted. So i cannot see how to tie the chat script in
