Known Behavior

z
If you create an L2TP destination profile
profileName
, establish tunnels with the
profile, and then remove the profile, you cannot subsequently create another
destination profile using that same
profileName
until all the tunnels drain from the
previous instance of this destination profile. If you do not wait, the E Series router
displays a message similar to the following:
l2tp: Discarding incoming sccrq from vr default, remote address 192.168.100.1 - no destination
profile.
If you do not want to wait for the tunnels to drain, use a different name for the
destination profile. [Defect ID 32973]
Line Module Redundancy
z
On E120 routers and E320 routers, redundant IOAs have a temperature sensor, and
the
show environment all
command lists the temperature of IOAs in their associated
slots.
On ERX routers, redundant I/O modules do not have a temperature sensor.
Therefore, the
show environment all
command output lists the primary I/O module
temperature in the slot of the line module that is responsible for the I/O module.
z
When you install an ES2-S1 Redundancy IOA with a hardware revision number of -02
or less in slot 0 or slot 11 of the E320 router or in slot 0 or the E120 router, do not install
an OCx/STMx ATM IOA or an OCx/STMx POS IOA in the lower (E320) or left (E120)
adapter bay of slot 1 or slot 12. When the spare line module is controlling another slot
and you revert back to the primary line module, the ATM or POS IOAs can become
unusable or cause the line module to reset. [Defect ID 69760]
Work-around
: This problem is not present for ES2-S1 Redundancy IOAs with a
hardware revision number of -03 or higher.
MLPPP
z
Do not configure both MLPPP fragmentation (with the
ppp fragmentation
command) and IP fragmentation of L2TP packets (with the
ip mtu
command) on
the same interface. Instead, you must choose only one of the fragmentation
configurations by setting it to the necessary value and set the other fragmentation
configuration to the maximum allowable value.
MPLS
z
Martini circuits configured on the ES2 10G LM act as true layer 2 tunnels, without
modifying the layer 2 headers. For this reason, Martini VLAN retagging is not currently
supported.
z
If you are upgrading to Release 7.1.0 or a higher-numbered release from a release
numbered lower than Release 7.1.0, and have inter-AS option B or C configurations,
you must explicitly configure MPLS on all inter-AS links, as in the following example:
host1#
configure terminal
host1(config)#
interface fastEthernet 2/0
host1(config-if)
#
ip address ...
host1(config-if)
#
mpls
If you do not explicitly configure MPLS on the links, the inter-AS feature will not work
properly.
z
You cannot use an underscore character (_) in an MPLS tunnel name.
