240 MES3000 Ethernet switch series
APPENDIX C DESCRIPTION OF SWITCH PROCESSES
Table - Description of switch processes
Transfer of packages between level 2 and network level
Program processing of intercepted ACL packets
Management and processing of AAA methods
AAA simulator for check of AAA methods
Control of device reboot in stack
BFD protocol implementation
Additional actions in stack (receipt of information about stack, indication, messages
exchange, change of unit id)
Processing of stack status commands: adding master/slave, studying topology, update of
software version of the slave
Bridge security - ARP Inspection, DHCP Snooping, DHCP Relay agent, IP Source
Guard, PPPOE Intermediate Agent
Bridge Management: EAPS, STP, operations with FDB (adding, removing notes), mirroring,
configuration of ports/VLAN, GVRP, GARP, LLDP, IGMP Snooping, IP multicast, OAM
Automatic synchronization of master and slave in stack
Copying of configuration files
Ethernet CFM implementation
Loading/rollout of configuration
Link Manager – task which control state of stack-links
Diacnostic ACTive tests - task in which VCT-tests are performed
Operation with file system
Server and Relay Agent DHCP
Distant Manager – receiving of information from remote units (firmware version, uptime,
active firmware image installation)
Dispatching of events in the stack. Dispatcher – processing of events from remote units
about state changes, fans, power supply state, thermosensors, SFP-tranceivers states.
DSPT allows receiving data about firmware version, serial number, firmware MD5 value)
Logging of events of exceeding CPU traffic threshold (cpu input-rate detailed)
Processing of Address Update event, lower level, transfer to higher level
Processing of events about change of port status, lower level, transfer to higher level
Processing of events of receipt of package from switch to CPU, lower level, transfer of
package to level 2
Processing of events of end of package sending from CPU to switch, lower level
Processing of packages output from lower level 2
Management of routing table and routing of packages
