Release Notes for Cisco Small Business SFE2000 Series 24-port 10/100 Ethernet Switches

Quality of Service Features

To overcome unpredictable network traffic and optimize performance, you can

apply Quality of Service (QoS) throughout the network to ensure that network

traffic is prioritized according to specific criteria. Your switch supports two modes

of QoS: basic and advanced.

•

Quality of Service Basic Mode

In basic QoS mode, it is possible to activate a trust mode (to trust VPT,

DSCP, TCP/UDP or none). In addition, a single access control list can be

attached to an interface.

•

Quality of Service Advanced Mode

Advanced Quality of Service mode specifies flow classification and

assigns rule actions that relate to bandwidth management. These rules can

be grouped into a policy, which can be applied to an interface.

Class Of Service 802.1p Support

The IEEE 802. 1 p signaling technique is an OSI Layer 2 standard for marking and

prioritizing network traffic at the data link/MAC sub-layer. 802. 1 p traffic is

classified and sent to the destination. No bandwidth reservations or limits are

established or enforced. 802. 1 p is a derivation of the 802. 1 Q (VLANs) standard.

802. 1 p establishes eight levels of priority, similar to the IP Precedence IP Header

bit-field.

Device Management Features

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.

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.
