You can configure bundles as follows:
On a COCX-F3 line module and its corresponding I/O modules, you can configure:
Up to 8 member links from different ports in the same bundle, with the following
restriction for MLPPP reassembly:
For a COCX-F3 line module with either a 12-port E3-12 FRAME I/O module or a
12-port CT3/T3 12 I/O module, the restriction is based on the ports on which
member links in the same bundle are configured.
A 12-port E3-12 FRAME I/O module and a 12-port CT3/T3 12 I/O module each
contain 12 ports numbered 0 through 11. When MLPPP reassembly is enabled, you
can configure a bundle with member links on the same port; on ports 0, 1, and 2;
on ports 3, 4, and 5; on ports 6, 7, and 8; or on ports 9, 10, and 11. However, the
router cannot properly reassemble fragments if you configure a bundle with member
links that span ports in different bundles; for example, on ports 0, 1, and 4.
When MLPPP reassembly is disabled, this restriction is not in effect; that is, member
links can span ports in different bundles.
Up to 12 bundles
On a cOCx/STMx line module and its corresponding I/O module, you can configure:
Member links from different OC3/STM1 ports in the same bundle, with the following
restrictions for MLPPP reassembly:
For a cOCx/STMx line module with a 4-port cOC3/STM1 I/O module, the restriction
is based on the ports on which member links in the same bundle are configured.
A 4-port cOC3/STM1 I/O module contains four ports numbered 0 through 3. When
MLPPP reassembly is enabled, you can configure a bundle with member links on
the same port, on ports 0 and 1, or on ports 2 and 3. However, the router cannot
properly reassemble fragments if you configure a bundle with member links that
span ports in different bundles; for example, on ports 1 and 2.
When MLPPP reassembly is disabled, this restriction is not in effect; that is, member
links can span ports in different bundles.
For a cOCx/STMx line module with a 1-port cOC12/STM4 I/O module, the restriction
is based on the STM1 (OC3) paths on which member links in the same bundle are
configured.
A 1-port cOC12/STM4 I/O module has four logical paths numbered 1 through 4.
When MLPPP reassembly is enabled, you can configure a bundle with member
links on the same path, on paths 1 and 2, or on paths 3 and 4. However, the router
cannot properly reassemble fragments if you configure a bundle with member
links that span paths in different bundles; that is, on paths 2 and 3.
When MLPPP reassembly is disabled, this restriction is not in effect; for example,
member links can span paths in different bundles.
Any combination of bundles that does not exceed the 336 available T1 channels (for
example, 336 single-link T1 bundles, 42 eight-link bundles, or 41 eight-link bundles
and 8 single-link bundles)
