Configuring Syslog Event Notifications
You can configure the following Syslog settings from the HTTP interface:
•
Enable Syslog: Place a check mark in the box provided to enable system logging.
•
Syslog Port Number: This field is read-only and displays the port number (514) assigned for system logging.
•
Syslog Lowest Priority Logged: The AP will send event messages to the Syslog server that correspond to the
selected priority and above. For example, if set to 6, the AP will transmit event messages labeled priority 0 to 6 to
the Syslog server(s). This parameter supports a range between 1 and 7; 6 is the default.
•
Syslog Host Table: This table specifies the IP addresses of a network servers that the AP will send Syslog
messages to. Click Add to create a new entry. Click Edit to change an existing entry. Each entry contains the
following field:
–
IP Address: Enter the IP Address for the management host.
–
Comment: Enter an optional comment such as the host name.
–
Status: The entry is enabled automatically when saved (so the Status field is only visible when editing an
entry). You can also disable or delete entries by changing this field's value.
Bridge
The AP is a bridge between your wired and wireless networking devices. As a bridge, the functions performed by the
AP include:
•
MAC address learning
•
Forward and filtering decision making
•
Spanning Tree protocol used for loop avoidance
Once the AP is connected to your network, it learns which devices are connected to it and records their MAC
addresses in the Learn Table. The table can hold up to 10,000 entries. To view the Learn Table, click on the Monitor
button in the Web interface and select the
The Bridge tab has four sub-categories.

Spanning Tree
A Spanning Tree is used to avoid redundant communication loops in networks with multiple bridging devices. Bridges
do not have any inherent mechanism to avoid loops, because having redundant systems is a necessity in certain
networks. However, redundant systems can cause Broadcast Storms, multiple frame copies, and MAC address table
instability problems.
Complex network structures can create multiple loops within a network. The Spanning Tree configuration blocks
certain ports on AP devices to control the path of communication within the network, avoiding loops and following a
spanning tree structure.
For more information on Spanning Tree protocol, please see Section 8.0 of the IEEE 802.1d standard. The Spanning
Tree configuration options are advanced settings. HP recommends that you leave these parameters at their default
values unless you are familiar with the Spanning Tree protocol.
