ERX routers display different behavior from E120 routers and E320 routers when

reporting modules as inactive.
ERX routers report a module as inactive when either:
 The I/O module is not present
 The primary line module is fully booted and ready to resume operation. In this
case, the standby is currently providing services.
E120 routers and E320 routers report a module as inactive when either:
 The primary line module has no IOAs.
 The primary line module has IOAs, but they have failed diagnostics.
 The standby line module has taken over for the primary line module, and has
control of the IOAs.
Because E120 and E320 routers can accommodate up to two IOAs per slot, at least
one IOA must be online. If the second IOA fails, the line module is still online, but does
not use both IOAs. You can ensure that every module is up and active in the system
and not in a failed state by issuing the show version all command.
If you enable engineering logs and set the control network logs to a level of notice or

lower (down from the default of error), you might see erroneous controlNetwork log
messages like the following that are generated because SNMP polling on line
modules (correctly) detects no fabric: [Defect ID 43168]
NOTICE 09/01/2002 18:47:52 CEST controlNetwork (slot 11): Control Bus Master slave error
0x5 while accessing slot
The show configuration category management syslog virtual-router default

command incorrectly displays logs for multiple syslog destinations when you add a
log to only one syslog destination. The show log configuration command shows the
correct configuration.
When you configure the GE-2 line module, the GE-HDE line module, or the ES2-S1

GE-4 IOA to operate as a shared tunnel-server module, the available bandwidth for
tunnel services is limited to 0.5 Gbps per module.
In releases numbered lower than Release 7.3.0, a dynamic tunnel-server port was

located on port 8 of the GE-HDE line module and GE-8 I/O module.
In Release 7.3.0 and higher-numbered releases, the dynamic tunnel-server port is
located on port 9. When you upgrade to Release 7.3.0, any existing tunnel-server port
configurations move from port 8 to port 9.
