daughter card to an isolated segment on a media module, the MAC daughter
card must be installed on that media module.
Because of the possibility of installing MAC daughter cards on the 8260 modules,
the 8260 modules are identified by slot and subslot identifiers. Note that the slot
and subslot identifiers are used in DMM commands to refer to the media
modules, management modules or daughter cards. The following is a summary
of how to identify the slot and subslot for each media module, management
module, and daughter card:
1. Each media module is always considered to be on the first subslot of the slot
2. If a MAC daughter card is installed on a media module, the daughter card is

Note
E-MACs installed on EC-DMM can collect detailed statistical information
about all the ShuntBus and Enhanced TriChannel Ethernet segments. This
statistical information includes network as well as module and port level
information. This information is collected for both 8260 and 8250 Ethernet
modules (note that 8250 Ethernet modules may attach to Ethernet_1 thru
Ethernet_3 segments only).
The E-MACs installed on the media modules can collect full statistics
(network, module and port level statistics) for Ethernet_4 thru Ethernet_8
segments only. For Ethernet_1 thru Ethernet_3, they can only collect network,
module and port level statistics for 8260 Ethernet modules, but for the 8250
modules attached to these segments they can only collect network level
statistics and cannot report module or port level statistics. This is due to the
use of parallel addressing by the 8250 modules. Therefore, if you are
planning to monitor Ethernet_1 thru Ethernet_3 segments which include 8250
Ethernet modules, you must ensure that the E-MACs used to monitor those
segments are installed on EC-DMM.
on which the media module is installed. For example, if you have installed a
24-port Ethernet media module in slot 2, this will be identified as module 2.1
(slot 2, subslot 1). This is regardless of the fact that the media module may
or may not have a MAC daughter card installed on it.
considered to be in subslot 2 of the slot in which the media module is
installed. For example, if the above mentioned 24-port media module had an
E-MAC installed on it, the E-MAC will be considered to be module 2.2,
whereas the 24-port module is 2.1. Figure 33 is an example of the output if
you display all the modules on slot 2.
