Hi I have one site with the 4G not working on an 897 router.no problems with the other 10 sites.
configuration of the interface
ip address negotiated
ip nat outside
ip virtual-reassembly in
dialer idle-timeout 0
dialer string lte
no peer default ip address
async mode interactive
crypto map cmap
see below the interface is up with IP address, it comes up when I initiate a ping as below
Cellular0 is up, line protocol is up
Hardware is 4G WWAN Modem - Global (Europe & Australia) Multimode LTE/DC-HSPA+/HSPA+/HSPA/U
Internet address is 10.96.248.57/32
MTU 1500 bytes, BW 50000 Kbit/sec, DLY 100000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation SLIP, loopback not set
Keepalive not supported
Last input 00:12:00, output never, output hang never Last clearing of "show interface" counters 1d06h
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Output queue: 0/10 (size/max)
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
3 packets input, 84 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicasts)

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

0 output errors, 0 collisions, 3 interface resets

DCD=up DSR=up DTR=up RTS=up CTS=up
and to test
IP route 220.127.116.11 255.255.255.254 cell 0
but when I ping 18.104.22.168 it times out.
also cannot ping 10.96.248.57 the IP address of the interface.
I do show IP route and see 10.96.248.57 is directly connected
#sh ip route | i 10.96
C 10.96.248.57/32 is directly connected, Cellular0
so there is a disconnect between the router and the cellular modem, the interface comes up with the first ping, and stays up till I clear the interface,but no there is no traffic passed
anybody any ideas on this one
I have the same issue.
What do you have as Line0 configuration and chat script?
Do you have this?
line 0/0/0 exec-timeout 0 0 ! Calls the chat-script script dialer LTE ! activates the script it did not work without it for GSM card. Not tested fir LTE card.
script activation LTE modem InOut no exec
for the 897 it is line 3
the modem side works as the interface picks up an IP address
script dialer lte
transport input all
transport output all
OK I found the problem
it was to do with the crypto map on the Cellular interface.
The Associated ACL had as last ACE 'ip permit any any'
removed entry and everything started working
