Release 11.0.2
When you configure 1:5 line module redundancy by using either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module, the spare R-Mid
OCX I/O module you install must have assembly number 350-00094-01 Rev.
A01 or later. Spare R-Mid OCX I/O modules with an earlier assembly number
are not supported for 1:5 redundancy configurations that use either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module.
There is a very small chance that some line modules can have an improperly
modified keying block that prevents the module from proper seating in the top
slot of an older ERX7xx chassis or a preproduction ERX310 chassis. For
example, this problem has been observed for an OCx/STMx module in slot 2 of
an early-test ERX310 chassis.
Work-around:
Remove the keying block to insert the module into the top slot,
or insert the module into a different slot.
HDLC
By design, on the cOC12/STM4 module you cannot delete a serial interface
while data for the interface is still enqueued. The enqueued data can drain only
when the interface is operationally up. Therefore you must ensure that the
interface is operationally up before you delete it. For example, if you have
issued the
shutdown
command for the interface before you try to delete the
interface, issue the
no shutdown
command, then delete the interface.
IP
The
ip tcp adjust-mss
command, which modifies the maximum segment size
for TCP SYN packets traveling through the interface, is not supported on the
ES2 10G LM or ES2 10G Uplink LM.
If you have enabled ipInterface logging at a priority of debug, the
acknowledgment that an interface has been deleted from the line modules can
return to the SRP module after the layers beneath IP have deleted their
interfaces. Consequently, the original name of the interface cannot be resolved
or displayed in the log, and the system instead displays the ifIndex of the IP
interface. This behavior has no functional effect other than that the log is
misleading. However, previous log events indicate that the interface deletion
was beginning.
When you want to use a configuration script to configure IP shared interfaces
that reference a physical interface, you must issue the
service show
configuration format 2
command before you generate the script. If the default
show configuration
format (format 1) is enabled instead, the generated script
cannot properly configure the IP shared interfaces because they are created
before the physical interfaces. To properly configure the shared interfaces in
this event, run the generated format 1 script twice.
