Field
Description
The following field values appear only when the port selected in the Unit/Port field is configured with a GBIC.
Pause Frames (Port 25 only)
Transmitted column: Indicates the total number of pause frames transmitted on this port. Pause frames cause the transmitting port to temporarily suspend the transmission of packets when the receiving port’s frame buffer is full (Gigabit ports only).
Received column: Indicates the total number of pause frames received on this port. Pause frames cause the transmitting port to temporarily suspend the transmission of packets when the receiving port’s frame buffer is full (Gigabit ports only).
System Log screen
The System Log screen (Figure 67) displays or clears messages obtained from system nonvolatile random access memory (NVRAM) or dynamic random access memory (DRAM) and NVRAM. When the switch is part of a stack configuration, the System screen displays only the data for the BayStack 420 Switch you are connected to through the Console/Comm port.
System Log messages operate as follows:
•NVRAM messages are retrievable after a system reset.
•DRAM messages can be viewed while the system is operational.
•All NVRAM and DRAM messages are time stamped.
•When you restart your system after a reset, the DRAM messages are deleted.
•After a reset, all messages stored in NVRAM are copied to DRAM (DRAM messages are not copied to NVRAM). The messages copied to DRAM are time stamped to zero (0).
To open the System Log screen:
Choose Display System Log (or press y) from the main menu.
