Introduction 23
BootP and DHCP Clients
DHCP enables additional setup parameters to be received from a network server upon system startup.
DHCP service is an on-going process. DHCP is an extension to BootP.
For more information on DHCP, see "Defining DHCP IPv4 Interface Parameters."
Quality of Service Features
Class Of Service 802.1p Support
The IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizing network
traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to the destination.
No bandwidth reservations or limits are established or enforced. 802.1p is a spin-off of the
802.1Q (VLANs) standard. 802.1p establishes eight levels of priority, similar to the IP Precedence
IPHeader bit-field.
For more information, see "Configuring Quality of Service."
Device Management Features
SNMP Alarms and Trap Logs
The system logs events with severity codes and timestamps. Events are sent as SNMP traps to a Trap
Recipient List.
For more information on SNMP Alarms and Traps, see "Defining SNMP Parameters."
SNMP Versions 1, 2 and 3
Simple Network Management Protocol (SNMP) over the UDP/IP protocol controls access to the system,
a list of community entries is defined, each of which consists of a community string and its access
privileges. There are 3 levels of SNMP security read-only, read-write, and super. Only a super user can
access the community table.
For more information, see "Defining SNMP Parameters".
Web Based Management
With the web based management, the system can be managed from any web browser. The system
contains an Embedded Web Server (EWS), which serves HTML pages, through which the system can be
monitored and configured. The system internally converts web-based input into configuration
commands, MIB variable settings and other management-related settings.
Configuration File Download and Upload
The device configuration is stored in a configuration file. The Configuration file includes both system
wide and port specific device configuration. The system can display configuration files in the form of a
collection of CLI commands, which are stored and manipulated as text files.
For more information, see "Managing Files."
