Multilink PPP Commands
XSR CLI Reference Guide 8-115
Mode
Dialer, Multilink, BRI Interface, and Controller configuration:
XSR(config-if< xx >)
and
XSR(config-controller<T/E xx >)
Default
Hostname
Example
The following example sets the PPP multilink endpoint value over virtual multilink interface 57 :
XSR(config)#interface multilink 57
XSR(config-if<M57>)#ppp multilink endpoint null
XSR(config-if<M57>)#ppp multilink endpoint hostname
XSR(config-if<M57>)#ppp multilink endpoint ip address 1.1.1.1
XSR(config-if<M57>)#ppp multilink endpoint string aaaaaaa
XSR(config-if<M57>)#ppp multilink endpoint phone 1234567890
ppp multilink fragment-delay
This command sets the maximum fragment delay interval in milliseconds. The value is used to
compute the maximum fragment size that can be sent over each member link in the bundle. The
maximum fragment size is calculated as:
Fragment size (in bytes) = fragment ‐ delay (ms) x link speed (kbps) / 8
Table 8 ‐ 1 below shows the relationship between maximum fragment delay and maximum
fragment size. Italicized figures indicate bytes .
Each MLPPP packet includes one fragment with an additional HDLC header (2 bytes), PID (2
bytes), MLPPP header (2/4 bytes for short/long sequence number format) and FCS (2 bytes).
The actual fragment size will be decided after the load balance over member link is taken into
account and should not exceed the maximum fragment size allowed. When the command is
mac
interface
IEEE 802.1 Global MAC address class is set with a MAC address of either
Fastethernet 1 or 2. fastethernet
string
PPP Magic Number class is specified. Instead of using the negotiated PPP
magic number, you can specify any string less than 20 characters.
phone
PSTN Directory Number class set with a phone number of no more than 15
digits.
Note: The maximum fragment size is limited to 1500 bytes.
