¾ Serviceability Tracing Commands
Debug commands provided to enable tracing of various protocols.
¾ Faster Initialization for Stacking Failover
Fast Reinitialization involves improvement in:
• Detection of Management Unit Failure
• Building Card Manager Database
• Application of saved configuration
Performance Improvements (based on Configuration File size) are:
• Default ~ 35%
• Medium ~ 50%
• Large ~80%
The impact is higher on large configuration files versus the smaller ones.
¾ Auto Config
Auto Config is a software feature which provides for the configuration of a switch automatically when the
device is initialized and no configuration file is found on the switch. Auto Config is accomplished in three
phases:
1. Configuration or assignment of an IP address for the device
2. Assignment of a TFTP server
3. Obtaining a configuration file for the device from the TFTP server
¾ DHCP Snooping
DHCP Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP
server. It filters harmful DHCP messages and builds a bindings database of (MAC address, IP address,
VLAN ID, port) tuples that are specified as authorized. DHCP snooping can be enabled globally and on
specific VLANs. Ports within the VLAN can be configured to be trusted or untrusted. DHCP servers must
be reached through trusted ports.
¾ DHCP L2 Relay
Permits L3 Relay agent functionality in L2 switched networks.
¾ sFlow
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is built
into network equipment and gives complete visibility into network activity, enabling effective management
and control of network resources.
