USB Modem
■
On SRX210, SRX100, SRX240, and SRX650 devices, when you restart fwdd at
the dial-out side, the umd interface goes down and the call never gets connected.
As a workaround, disable the dialer interface and restart the forwarding daemon.
Enable the dialer interface when the forwarding daemon is up and running. As
a result the dial-out side reconnects with the dial-in side successfully.
Perform the following steps:
1.
Disable the dialer interface.
root@noky# set interfaces dl0 disable
root@noky# commit
2.
Restart the forwarding daemon.
root@noky# run restart forwarding Forwarding Daemon started, pid 1407
root@noky# delete interfaces dl0 disable
root@noky# commit
3.
Enable the dialer interface.
root@noky# delete interfaces dl0 disable
root@noky# commit

On SRX210 High Memory devices and J6350 devices, packet loss is seen during
rapid ping operations between the dialer interfaces when packet size is more
than 512 Kbps. [PR/484507]
■
On SRX210 High Memory devices, the modem interface can handle bidirectional
traffic of up to 19 Kbps. During oversubscription of 20-Kbps or more traffic, the
keepalive packets are not exchanged and the interface goes down. [PR/487258]
■
On SRX210 High Memory devices, IPv6 is not supported on dialer interfaces
with a USB modem. [PR/489960]
■
On SRX210 High Memory devices, http traffic is very slow through the umd0
interface. [PR/489961]
■
On SRX210 High Memory devices, on multiple resets of the umd0 interface, the
umd0 interface keeps flapping if the d10 (dialer) interface on either the dialin
or dialout interface goes down because no keepalive packets are exchanged. As
a workaround, increase the ATS0 value to 4 or greater. [PR/492970]
■
On SRX100, SRX210, SRX240, and SRX650 devices, the call terminates if you
remove and insert a USB modem. [PR/491820]
■
On SRX210 High Memory devices and J6350 devices, the D10 link flaps during
long-duration traffic of 15 Kbps and also when packet size is 256 Kbps or more.
