Configuring LPs and LAN Cards 6-5
Protocol 1–5
specifies the protocols that will be loaded onto the LP software on boot-up.
0
= None
1
= X.25
2
= Frame Relay
3
= Async
4
= SDLC
5
= BSCI (BSC Interactive)
7
= IP
8
= SNMP
9
= RIP
11
= TRNK (Trunk)
12
= IPX
Note these requirements and recommendations:
●
Each RLP must have X.25 configured.
●
RIP is valid only if IP is already configured on the RLP.
●
SNMP will not work unless IP is also configured in the node. IP can be, but does
not have to be, on the same RLP.
●
IP, IPX, and SNMP should not be configured on more than one RLP each. (All
three can be configured on the same or different RLPs.)
●
To configure a protocol on a port, the protocol must first be configured on the
LP containing the port.
E1-specific Parameters
Coding
is the line coding technique used to carry clock signals.
Framing
is the frame format. G.704 is a CEPT standard, with a set value.
Line Service
specifies (as configured) that the RLP will use all of the DS0 channels on the E1 line.
Line Build Out
is the distance from the LP to the external T1/E1 device. G.703 is a CEPT standard,
with a set value.
Clocking
is the clocking mode in which the LP runs:
0
= Master,
1
= Slave
CRC-4 Disabled
disables (as configured) the generation of CRC-4 (polynomial X4 + X + 1).
Channel Signalling
is the mode of the CEPT interface.
National Use Bit “n”
is the setting of the national use bits in the non-frame alignment signal. National use
bits 1-5 correspond to data bits 4-8 in the non-frame alignment signal. National use
bits are reserved for use within a country. If the signal will cross an international
border, the national use bits should be
Off
.
International Use Bit 0
is the setting of bit 0, which is transmitted as the most significant bit of the frame
alignment signal when CRC-4 is disabled.
