TOS for Voice Data
Shows the priority for voice data streams. The value must be entered in hexadecimal
format translated from binary, and can use either IP Precedence or Differentiated Services
Code Point (DSCP). See Type of Service (ToS) on page 28-2 above for a more detailed
explanation of ToS.
TOS for Voice Signaling Data
Shows the priority for voice signaling data streams. The value must be entered in hexa-
decimal format translated from binary, and can use either IP Precedence or Differentiated
Services Code Point (DSCP). See Type of Service (ToS) on page 28-2 above for a more
detailed explanation of ToS.
TOS Mask for both TOS Value
Shows the mask bits for both voice data and signaling data.
Signaling IP Address
When a data frame cannot be identified by the ToS voice data or ToS signaling data, the
Signaling IP Address is checked. Matched frames are loaded on a High Priority Software
Queue and a Nominal Hardware Queue.
Signaling IP Mask
The mask associated with the Signaling IP Address described above.
KeepAlive Up Count
If the switch detects that a port may be down, it will generate echo message requests to
the far end of the connection. The KeepAlive Up Count is the number of requests sent
from the port when the port transitions from Down to Up, to verify the status of the port.
KeepAlive Down Count
If the switch detects that a port may be down, it will generate echo message requests to
the far end of the connection. The KeepAlive Down Count is the number of requests sent
from the port when the port transitions from Up to Down, to verify the status of the port.
This only displays if the port is using PPP as its encapsulation type.
KeepAlive Timeout
The number of 100 millisecond increments between generated echo message requests.
This only displays if the port is using PPP as its encapsulation type.
Loopback Timeout
Sets the transition time between proprietary messages sent over the link. These messages
are analyzed to determine whether the link is in a loopback state. This only displays if the
port is using Frame Relay as its encapsulation type.
