Note:
1. Do NOT interrupt power and network connections during software upgrading. If network is interrupted during
the process, you must re-enter the upgrade screen and re-upgrade the software.
2. To return to management interface when you already enter the upgrade screen, simply click
Back
.
But you
cannot return to the management interface if upgrade is in process or upgrade fails.
3.3 Port Management
3.3.1 Port Configuration
1. Port Configuration
This section allows you to configure link rate, duplex mode, flow control and MAC address learning, priority and
broadcast storm control settings on each individual port as well as enable or disable a particular port. You can select
10Mbps half-duplex, 10Mbps full-duplex, 100Mbps full-duplex, 100Mbps half-duplex, 1000 full-duplex (only
available for ports 25-26) or auto-negotiation for the port to operate on. The default mode is Auto
(auto-negotiation), in which the port automatically negotiates with the link partner for optimum speed/duplex mode.
In this mode, a port communicates and negotiates automatically with linked partner to determine an optimum
speed/duplex mode. Before selecting other options than “Auto”, ensure that the linked partner is operating in the
same mode or in auto-negotiation mode; otherwise, communication may fail.
For packets not carrying 802.1Q tag, the switch uses port priority as 802.1p priority to look up in local priority
mapping table and mark a local priority for it. In case of congestions, the switch forwards packets based on their
priority levels.
Flow control regulates the rate of data transmission between two nodes to prevent a fast sender from outrunning a
slow receiver, so that the receiving node does not drop packets due to buffer overflow.
Broadcast storm control effectively prevents various broadcast storm, avoiding network congestion and ensuring a
reliable network.
With MAC address learning feature, the switch identifies MAC addresses of NICs from all nodes and register them
in its MAC address table so as to speed up forwarding frames by looking up destination MAC addresses of received
frames in its MAC address table.
How you configure each port here will affect port mirroring, port rate limit and aggregation features, etc.
