1 BitStorm 1900 Access Multiplexer Elastic Networks
1-10 BitStorm 1900™ Installation and Maintenance Guide 08-01101-01, Rev. 1.50
WAN Interface Cards
The BitStorm 1900 supports two (2) types of WAN interfaces:
• MIU (Management Interface Card) - supports 4212, 6306, 6224,
10306, and 10224 modem cards
• Switch Card - supports 4212 modem cards
MIU SNMP Functionality
The MIU provides remote monitoring and configuration functionality
via SNMP (Simple Network Management Protocol). Through the
SNMP agent, users can remotely manage and configure modem set-
tings and monitor the performance statistics of all modems in the Bit-
Storm 1900 system.
The MIU SNMP agent supports the SNMPv1/RFC 1157 protocol and
supports RFC 1213 MIB II interface groups and the RFC 1493 Bridge
MIB. The MIU SNMP agent also includes an Elastic Networks’ Ether-
Loop private MIB. In order to manage the SNMP agent, the user must
load the Elastic Networks’ private MIB into the user’s SNMP Network
Manager using the procedure accompanying the specific Network
Management Software (i.e., HP Openview, etc.).
A list of all supported MIBs and the Elastic Networks’ private MIB can
be found in "Appendix C: SNMP MIBs‚" on page 163 of this document.
Elastic Networks’ private MIBs can be downloaded from the Elastic
Networks ftp site. Contact the Elastic Networks Customer Satisfaction
organization for instructions on how to access the FTP site. (Refer to
Table 4-1, “Customer Satisfaction Contact Information,” on
page 131.)
Mixing CO Modem Cards
When using an MIU, it is possible to fill a BitStorm 1900 shelf with
different modem cards (i.e., two 4212 CO modem cards, four 6306 or
10306 CO modem cards, and four 6224 or 10224 CO modem cards).
However, if a Switch Card is used instead of an MIU, only 4212 CO
modem cards can be installed in the BitStorm 1900 shelf. Switch cards
only support the 4212 modems.
