Ethernet Routing Switch 8600 module fundamentals
For table entry usage information, see Nortel Ethernet Routing Switch
8600 Planning and Engineering — Network Design, NN46205-200.
M mode configuration requirements
M mode supports the Ethernet Routing Switch 8600 Release 3.x feature
set. Full support of M mode requires the following configuration conditions:
•
The chassis must include at least one 8691 SF/CPU module.
•
All modules installed in the chassis must minimally support 128 000
table entries. M modules (8632TXM, 8648TXM, 8608GBM, 8608GTM,
8683POSM, 8672ATMM, and 8672ATMM modules) support 128 000
table entries.
•
M modules require Ethernet Routing Switch 8600 Release 3.3 or later.
•
M mode must be enabled.
•
If your system includes R modules, M modules, or E modules, see
Nortel Ethernet Routing Switch 8600 Administration, NN46205-605
for configuration information to ensure that the switch reboots in the
desired mode.
If M mode is enabled and one or more modules installed in the chassis
is an E module (32 000 table entries), the E modules are disabled. This
protects the system forwarding tables from lost entries.
M modules offer additional memory to support large routing tables such as
those found in BGP implementations. M mode, or 128 000 records mode,
requires the 8691SF/CPU module. When enabled, this mode allows M
modules to use their full capabilities (128 000 records). When disabled,
this mode allows the M modules to operate in 32 000 records mode.
R mode configuration requirements
R mode supports the Ethernet Routing Switch 8600 4.x and later feature
set. Full support of R mode requires the following configuration conditions:
•
The system must include only R series modules. You can configure a
system with a mix of R, M, or E modules in R mode; however, M, E,
or pre-E modules are not enabled. For information about configuring
R modules in R mode, see Nortel Ethernet Routing Switch 8600
Administration, NN46205-605.
•
The system must include at least one 8692 SF/CPU module.
R modules do not boot with 8691 SF/CPU modules.
•
R modules require Ethernet Routing Switch 8600 Release 4.0 or later.
•
R mode must be enabled.
