• a software process that enters an infinite loop
The software lock-up detect feature monitors processes to ensure that the software functions within
expected time limit.
The CPU logs detail about suspended tasks in the log file. For additional information about log files,
see Managing Faults on Avaya Virtual Services Platform 7200 Series and 8000 Series,
NN47227-702.
Jumbo frames
Jumbo packets and large packets are particularly useful in server and storage over Ethernet
applications. If the payload to header relation increases in a packet, the bandwidth can be used
more efficiently. For this reason, increasing Ethernet frame size is a logical option. The switch
supports Ethernet frames as large as 9600 bytes, compared to the standard 1518 bytes, to transmit
large amounts of data efficiently and minimize the task load on a server CPU.
Tagged VLAN support
A port with VLAN tagging activated can send tagged frames. If you plan to use Jumbo frames in a
VLAN, ensure that you configure the ports in the VLAN to accept Jumbo frames and that the server
or hosts in the VLAN do not send frames that exceed 9600 bytes. For more information about how
to configure VLANs, see Configuring VLANs, Spanning Tree, and NLB on Avaya Virtual Services
Platform 7200 Series and 8000 Series, NN47227-500.
10/100/1000BASE-TX Auto-Negotiation recommendations
Auto-Negotiation lets devices share a link and automatically configures both devices so that they
take maximum advantage of their abilities. Auto-Negotiation uses a modified 10BASE-T link integrity
test pulse sequence to determine device ability.
The Auto-Negotiation feature allows the devices to switch between the various operational modes in
an ordered fashion and allows management to select a specific operational mode. The Auto-
Negotiation feature also provides a parallel detection (also called autosensing) function to allow the
recognition of 10BASE-T, 100BASE-TX, 100BASE-T4, and 1000BASE-TX compatible devices,
even if they do not support Auto-Negotiation. In this case, only the link speed is sensed; not the
duplex mode.
Avaya recommends the Auto-Negotiation configuration as shown in the following table, where A and
B are two Ethernet devices.
Important:
If Auto-Negotiation is disabled, the 8424GT ESM, the 8424XT ESM and the VSP 7254XTQ
switch do not support half-duplex.
