Introduction 33BootP and DHCP ClientsDHCP enables additional setup parameters to be received from a network server upon systemstartup. DHCP service is an on-going process. DHCP is an extension to BootP.For more information on DHCP, see "Defining DHCP IP Interface Parameters."Quality of Service FeaturesClass Of Service 802.1p SupportThe IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizingnetwork traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to thedestination. No bandwidth reservations or limits are established or enforced. 802.1p is a spin-off ofthe 802.1Q (VLANs) standard. 802.1p establishes eight levels of priority, similar to the IPPrecedence IP Header bit-field.For more information, see "Configuring Quality of Service."Device Management FeaturesSNMP Alarms and Trap LogsThe system logs events with severity codes and timestamps. Events are sent as SNMP traps to aTrap Recipient List.For more information on SNMP Alarms and Traps, see "Defining SNMP Parameters."SNMP Versions 1, 2 and 3Simple Network Management Protocol (SNMP) over the UDP/IP protocol controls access to thesystem, a list of community entries is defined, each of which consists of a community string and itsaccess privileges. There are 3 levels of SNMP security read-only, read-write, and super. Only a superuser can access the community table.For more information, see "Defining SNMP Parameters".Web Based ManagementWith the web based management, the system can be managed from any web browser. The systemcontains an Embedded Web Server (EWS), which serves HTML pages, through which the systemcan be monitored and configured. The system internally converts web-based input intoconfiguration commands, MIB variable settings and other management-related settings.Configuration File Download and UploadThe device configuration is stored in a configuration file. The Configuration file includes bothsystem wide and port specific device configuration. The system can display configuration files inthe form of a collection of CLI commands, which are stored and manipulated as text files.For more information, see "Managing Files."
