Trunking is a way to carry traffic from several VLANs over a point-to-point link between the two devices. Two ways in which Ethernet trunking can be implemented are: 1) ISL - InterSwitch Link (Cisco proprietary protocol, and not supported by the 2940 or 2950 series switches) 2) 802.1Q (Institute of Electrical and Electronics Engineers (IEEE) standard) For Catalyst 2900XL/3500XL/2940/2950/2970 Switches: Catalyst 2940 and 2950 series switches only support 802.1q trunking, and do not support ISL trunking. On a 4 MB DRAM Catalyst 2900XL switch, trunking is only supported with the following trunking-capable modules: WS-X2914-XL-V: 4-port 10/100 ISL/802.1Q switch module WS-X2922-XL-V: 2-port 100BaseFX ISL/802.1Q switch module WS-X2924-XL-V: 4-port 100BaseFX ISL/802.1Q switch module WS-X2931-XL: 1000BaseX uplink for Catalyst 2900 XL WS-X2932-XL: 1000BaseT uplink for Catalyst 2900 XL To get the compactability chart please refer; http://www.cisco.com/en/US/tech/tk389/tk815/technologies_configu

Configuring Network for a Linux System Edit configuration files stored in /etc/sysconfig/network-scripts/ You can configure network card by editing text files stored in / etc/sysconfig/network-scripts/ directory . First change directory to /etc/sysconfig/network-scripts/: # cd /etc/sysconfig/network-scripts/ Edit / create files as follows: • /etc/sysconfig/network-scripts/ifcfg-eth0 : First Ethernet card configuration file • /etc/sysconfig/network-scripts/ifcfg-eth1 : Second Ethernet card configuration file For edit/create first NIC file, type command: # vi ifcfg-eth0 Modify as follows: # Intel Corporation 82573E Gigabit Ethernet Controller (Copper) DEVICE=eth0 BOOTPROTO=static DHCPCLASS= HWADDR=00:30:48:56:A6:2E IPADDR=10.10.29.66 NETMASK=255.255.255.192 ONBOOT=yes Save and close the file. Define default gateway (router IP) and hostname in /etc/sysconfig//network file: # vi /etc/sysconfig/network Append/modify configuration as follows: NETWORKING=yes HOSTNAME=www1.nixcraft.in GATEWAY=
