Table 10: System Description Fields (continued)
Field
Description
Service Port IP Address The IP address assigned to the service port. The service port provides remote
management access to the device. Traffic on this port is segregated from operational
network traffic on the switch ports and cannot be switched or routed to the operational
network.
System Object ID
The base object ID for the switch's enterprise MIB.
System Up Time
Displays the number of days, hours, and minutes since the last system restart.
Current SNTP
Synchronized Time

Switch Configuration
IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed and dropping
all traffic for small bursts of time during the congestion condition. This can lead to high-priority and/or
network control traffic loss. When 802.3x flow control is enabled, lower speed switches can
communicate with higher speed switches by requesting that the higher speed switch refrains from
sending packets. Transmissions are temporarily halted to prevent buffer overflows.
