Security
User access security can be implemented using the following functions of the
8275-416:
v
User Accounts: The switch supports up to six accounts (one user with read/write
status and five with read-only status) for terminal interface and Web access.
Access to the switch configuration panels is password protected. Only one user
name with read/write status is allowed to be configured, which prevents potential
conflicts in configuration changes. The default Read/Write user name is:
admin ,
and the default password consists of blanks (no password). If you lose the
password, contact your IBM service representative.
v
SNMP read/write protection based on community name.
Reliability and serviceability
The switch:
v
Provides a comprehensive power-on self-test (POST) that ensures that all of its
components are functioning correctly.
v
Controls a seven-segment LED that allows you to follow the boot sequence.
v
Allows you to download software upgrades using any of the management
methods.
v
Allows you to implement parallel paths for network traffic through the use of
spanning tree protocol (STP), which provides a level of fault tolerance and
ensures that:
– Redundant paths are disabled when the main paths are operational
– Redundant paths are enabled if the main paths fail
v
Allows you to configure a port to “see” traffic going into and out of another port
on the switch (port monitoring).
v
Provides statistics for all ports.
Performance
High performance, Layer 2 switching for the switch consists of:
v
Switching for up to 32 ports
v
Supporting up to 12 000 end stations
v
Processing 64-byte packets at the following rates:
– 14 880 packets per second to 10-Mbps ports.
– 148 800 packets per second to 100-Mbps ports
v
Detecting broadcast storms and preventing them from impacting the network
(Broadcast Storm Recovery).
