ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
Switching Commands 3-203
v1.0, November 2010
debug isdp packet
This command enables tracing of ISDP packets processed by the switch. ISDP must be enabled on
both the device and the interface in order to monitor packets for a particular interface.
no debug isdp packet
This command disables tracing of ISDP packets on the receive or the transmit sides or on both
sides.
Priority-Based Flow control commands
Ordinarily, when flow control is enabled on a physical link, it applies to all traffic on the link.
When congestion occurs, the hardware sends pause frames that temporarily suspend traffic flow.
Pausing traffic helps prevent buffer overflow and dropped frames.
Priority-based flow control provides a way to distinguish which traffic on physical link is paused
when congestion occurs, based on the priority of the traffic. An interface can be configured to
pause only high priority (i.e., loss-sensitive) traffic when necessary to prevent dropped frames,
while allowing traffic that has greater loss tolerance to continue to flow on the interface.
Priorities are differentiated by the priority field of the IEEE 802.1Q VLAN header, which
identifies an IEEE 802.1p priority value. In FASTPATH, these priority values must be mapped to
internal class-of-service (CoS) values.
ISDP IP Address Table Full Displays the number of times a neighbor entry was added to the table
without an IP address.
