Class Of Service 802.1p Support
The IEEE 802.1p signaling technique is an OSI Layer 2 standard for tagging and prioritizing
network traffic at the data link/MAC sub-layer. The 802.1p traffic is classified and sent to the
destination; no bandwidth reservations or limits are established or enforced. The 802.1p standard
establishes eight levels of priority, similar to the IP Precedence IP Header bit-field.
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.
For information about enabling QoS Basic Mode, see "Configuring Basic QoS Mode."
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.
For information about enabling QoS Advanced Mode, see
"
Configuring Advanced QoS Mode."
Device Management Features
SNMP Alarms and Trap Logs
The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a
trap recipient list.
For information about SNMP Alarms and Traps, see "Defining SNMP Parameters."
Web Based Management
You can manage the system from any web browser. The switch contains an embedded web server
that serves HTML pages that you can use to monitor and configure the system.
Configuration File Download
The switch’s configuration file includes both system-wide and port-specific device configuration
data. You can display configuration files through CLI commands.
For information about downloading configuration files, see "Downloading Files."
Software Download
Software download enables storage of backup firmware images. For information about downloading
the software, see
