Modem Link: PPP
Next PPP SLIP Prev
Modem Port Link Layer Protocol. Specifies the link layer protocol f or the mode m port if the
Modem Use configuration option is set to Mgmt.
PPP – Specifies PPP as the link layer protocol for the IP management link on the modem
port.
SLIP – Specifies SLIP protocol as the link layer pro tocol f or th e IP mana gement l ink on the
modem port. The modem port must be configured for asynchronous operation to support
SLIP.
NOTE: This configuration option is available on standalone DSU/CSUs only. ●
Aux IP Adr:
Next Edit Clear Prev
IP Address for the Auxiliary Port. Specifies the IP address for the auxiliary port if the Aux
Use configuration option is set to Mgmt or Daisy. The aux iliary port only supports the PPP
link protocol.
Edit – Allows you to edit and/or display the IP address for the auxiliary port.
Clear – Allows you to clear the IP address for the auxiliary port. The IP address is set to
000.000.000.000.
NOTE: This configuration option is available on Model 3164 DSU/CSUs only. ●
Aux NetMask:
Next Edit Clear Prev
Subnet Mask for the Auxiliary Port. Specifies the subnet mask for the auxiliary port if the
Aux Use configuration option is set to Mgmt or Daisy.
Edit – Allows you to edit and/or display the subnet mask for the auxiliary port.
Clear – Allows you to clear the subnet mask for the auxil iary port. The subnet ma sk is s et
to 000.000.000.000. If the subnet mask is 000.000.000.000, the IP protocol creates a
default subnet mask based on the class of the IP address (Class A: 255.000.000.000,
Class B: 255.255.000.000, or Class C: 255.255.255.000).
NOTE: This configuration option is available on Model 3164 DSU/CSUs only. ●
IPBusMast: Disab
Next Enab Disab Prev
Setting the IP Bus Master. Specifies whether or not a particular carrier-mounted unit is the
IP Bus Master. There can only be one IP Bus Master per 3000 Series Carrier. Typically,
the carrier-mounted unit that has the SNMP/Telnet ma nagemen t sys tem conn ected to it i s
the IP Bus Master. This allows for faster access to the remaining carrier units. If an
SNMP/Telnet management system is connected to another carrier-mounted unit (i.e. not
the IP Bus Master) and the SNMP/Telnet management system tries to access another
carrier-mounted unit, the data has to be routed to the IP Bus Master first. On ce the IP Bus
Master receives the data, it is routed to the appropriate slot.
Enab – This unit is the IP Bus Master. Only one IP Bus Master is allow ed per 30 00 Series
Carrier.
Disab – This unit is not the IP Bus Master.
NOTE: This configuration option is available on carrier-mounted DSU/CSUs only. ▲
