4.4 Software Architecture
4.4.1 System Software Architecture
ZXR10 8900E series switches are multi-layer switches that have L2 switching, L3 routing
and MPLS L2/L3VPN and that support multiple service functions. They can provide L3
and L3 wire-speed switching and routing and QoS guarantee. The system software
implements system management, control and data forwarding. Its basic work includes
system startup, system configuration management, protocol running, table maintenance,
switching chip setting and state control as well as forwarding of some special messages.
The software system realizes the following functions:
Realize main L2 protocol functions, including 802.1D STP protocol, 802.1P priority
level control, 802.1Q VLAN related functions and 802.3ad link aggregation function;
Support IPv4/IPv6 protocol stack and basic routing protocol;
Realize multicast protocol and support IPTV deployment;
Realize ACL and DHCP multi-layer services;
Realize partial broadband access function;
Realize the Agent function of network management protocol SNMPv3;
The user can perform network management for Ethernet switch via serial port
terminal, Telnet/SSH and SNMP Manager, including: network configuration
management, fault management, performance management and security
management;
Software version can be upgraded smoothly; the active and standby protocol
processing cards and switching network cards support online upgrade;
