6 Recommendations and feature-specific information about release 2.0.7.8
Recommendations and miscellaneous information
Note the following recommendations and miscellaneous information about
Passport 1000 Series switch software release 2.0.7.8:
• Changes have been made to Passport 1000 series switches from software
release 2.0.7.3 onwards in terms of selection of the best path to an ASBR if
more than one path exists. Due to these changes, Nortel Networks
recommends that you not interconnect a switch running software release
2.0.7.3 or higher to a switch running a software release 2.0.7.2 or lower.

• Passport 1000 Series switch software release 2.0.7.8 does not support global
filters. Configuration information relating to global filters is ignored. When
booting up with software version 2.0.7.8, the following message is displayed
on the screen:
Global filters are not supported in this release.
• When you create a MultiLink Trunking (MLT) group through the command
line interface (CLI), the resulting MLT is put into the default VLAN (VLAN
1). The MLT should then be assigned to other VLANs as appropriate.
• Always set a specific Enforce Operational Configuration (EOC) mode (refer
to the Passport 1000 Series switch software release 2.0 release notes for more
information) instead of allowing the default EOC mode (which is to the
lowest-level module in the switch) in order to avoid losing functionality in
case a lower-revision module is installed in the switch.
• Terminology has been modified in Device Manager and the CLI so that
"trunk" is used only in reference to MultiLink Trunking (MLT). What were
previously referred to as trunk ports (in contrast to access ports) are now
referred to as tagged ports.
• Gigabit LinkSafe
autonegotiation to False is not supported on gigabit LinkSafe modules in
redundant configurations. However, autonegotiation can be set to False if a
gigabit LinkSafe module is connected in a nonredundant setup to a gigabit
module not supporting autonegotiation.
