In a Simple Network Management Protocol (SNMP) managed
environment the DMM acts as the SNMP agent, responding to SNMP
requests and generating SNMP traps.
− Telnet support
Using Telnet you can log in remotely to any DMM on the network and
manage it from the remote station. You can also use Telnet from the
terminal attached to the DMM to log in to any other device which
supports Telnet.
− Inventory
The DMM provides a complete inventory of the hub including power
supplies, fans and modules installed in the 8260.
− Staging
The media modules save their configuration information in an onboard
non-volatile RAM (NVRAM). This means flexibility for network managers
as they can configure the modules at a central site and then send them
out to the remote locations for installation.
− Power management
The DMM when used in conjunction with the fault tolerant controller
module can be used to manage the power subsystem. For example, it
can set power classes for modules and turn power fault tolerance on and
off.
− Mapping
DMM allows you to display a detailed topological ring map including
address-to-port mapping about the token-ring segments on the network.
4.1.1 IP Addressing for DMM
Because of the centralized approach to management used in the 8260 there is a
need for a new approach for assigning IP addresses to DMM when compared to
the 8250. This is because, you may use a single DMM to communicate with IP
stations attached to multiple different segments on the backplane.
The following is the summary of the steps you must take, in order to enable
DMM to use IP to communicate with the other stations:
1. Assign an IP address to each of the networks on the backplane.
2. Assign an E-MAC or T-MAC to that network. This results in the T-MAC or
E-MAC assuming the IP address of that network.
3. The DMM will now be able to communicate across that network using the IP
address assigned to the T-MAC or E-MAC. In fact, DMM will send the IP
packets over MLAN to the appropriate E-MAC or T-MAC and the E-MAC or
T-MAC will forward it over the segment to which it is attached.
Note: A single DMM can communicate across multiple backplane segments
as long as there is a daughter card assigned to each of those backplane
segment.
