Note:
When using line cards introduced prior to the “AA” series, SNA/DLC/NetBIOS traffic
may not bridge properly. The issue in bridging DLC packets occurs where the length field
within an IEEE 802.3 frame indicates less than 46 bytes of data.
The X-Pedition removes the length field information of incoming IEEE 802.3, 802.2, and
Ethernet SNAP packets, then recalculates the field prior to re-transmission. Consequently,
the calculation is based on the length of the entire data field. A packet entering the
X-Pedition whose length field indicates a data field of less than 46 bytes will exit with the
length field recalculated incorrectly. This can be a problem with LLC2 and legacy IPX
applications. Typically, such packets exist only in SNA and NetBIOS/NetBEUI
environments.
Table 2. X-Pedition 8600 Switching Fabric module LEDs
LED
Condition
Description
Offline
Amber
The module is offline (powered off) and is ready for hot swap.
The Offline LED also lights briefly during a reboot or reset of the X-Pedition and
goes out as soon as the control module discovers and properly initializes the
switching fabric module.
Online
Green
The module is online and is ready to receive, process, and send packets if
configured to do so.
Active
On
The switching fabric module is actively receiving, processing, and sending
packets.
