ACS-MCC Card User Screens and Settings MCC Card

NETMASK

The NETMASK setting together with the IP ADDR identifies the network for this port.

FORMAT

The Format setting determines the format of the information received from the remote system unit. For the numbered ports (1-128), the options are b7r (for T1 links) and b4r (for E1 links). For ports C1-C3, the options are hdlc (high-level data link control) and fr (frame relay). If fr is selected, the user must select a DLCI (data link connection identifier), which corresponds to the virtual circuit number of the frame relay destination address. When more than one TS is selected, the MTU is 1,500. The internal MTU is expanded by four on the WAN segment to allow 1,500 byte frames to pass with the addition of the frame relay header without fragmentation. When fr is selected, more than one TS must be allocated.

RIP

When the Routing Information Protocol (RIP) setting is off (default), no RIP traffic is allowed into or out of the Ethernet interface. Setting this variable to rx allows incoming RIP traffic only, while setting it to tx allows only outgoing RIP traffic. Setting this variable to rx/tx allows both incoming and outgoing RIP traffic.

Note: Due to the high number of interfaces on the ACS-MCC card and the relatively low bandwidth of the Munich interfaces, the user should be cautious about implementing the RIP option, as there is a substantial risk of broadcast storms causing congestion in the network.

SH

When the Split Horizon (SH) variable is set to on, the ACS-MCC card does not automatically send RIP information along routes it "learned" through the same interface. The default is off.

WEIGHT

The Weight parameter assigns a weighting variable to the specified interface. The number must be between 1 and 15. The default is 1.
