Token Ring Resources Manual Installation and Configuration Manual Installation and Configuration For Non-PCI Systems HP recommends that you install your Token Ring software using swinstall and configure it using SAM. Follow the steps below to manually install and configure your Token Ring product. Refer to detailed instructions in the Installing and Administering LAN/9000 Software manual for additional information. The section for manually configuring a PCI system follows this one. 1.
Token Ring Resources Manual Installation and Configuration This step is equivalent to configuration using SAM. Token Ring configuration is kept in the netconf and hptokenconf files. See “Editing /etc/rc.config.d/netconf” in Chapter 3 of the Installing and Administering LAN/9000 Software manual for details. Note that for Token Ring, the encapsulation method is not configurable. The Internet configuration information in the netconf file should be similar to the information displayed in the example below.
Token Ring Resources Manual Installation and Configuration This example assumes the NMID of the Token Ring link is 5 (use lanscan(1M) to find the NMID). lanadmin(1M) sets the station address and the MTU size (if different from the default). ifconfig(1M) configures the IP address and masks. 7. Refer to the Installing and Administering LAN/9000 Software manual for the edits required to /etc/hosts, /etc/services, /etc/networks, and /etc/protocols.
Token Ring Resources Manual Installation and Configuration 1. Edit /etc/rc.config.d/pcitrconf and specify the parameters for each interface that is to be enabled. Follow the instructions in the file on how to configure each interface. Please note that setting incorrect parameters can render your network inoperable and will prevent the Token Ring link from connecting to the network. Please exercise caution while modifying parameters. Please note the following: a. Starting with B.11.00.
Token Ring Resources Manual Installation and Configuration support MTU’s as low as 4540 bytes. MAUs support 18000, but they do not support full duplex (FDX). Consult your switch manual before configuring the MTU. Also note that HP-PB (J2166A) and EISA (J2165A and J2638AA) currently support an MTU of 4170 bytes. If PCI Token Ring is to be connected to a network containing HP-PB Token Ring, it is best to set PCI Token Ring’s MTU at 4170.
Token Ring Resources Manual Installation and Configuration NOTE If full-duplex is enabled and the requirements of g.1 through g.3 above are satisfied, the adapter will sense and configure itself to 100 Mb/s operation regardless of the speed setting. This is not supported. A 100 Mb/s switch port cannot support 4/16 Mb/s operation. Manually setting 4 or 16 Mb/s when A5783A is connected to a 100 Mb/s switch port is not supported. Connecting A4930A to a 100 Mb/s switch port is not supported. Starting with B.
