16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Configuration Examples for the 16- and 36-Port Ethernet Switch Module The following example illustrates the configuration on the PC: interface FastEthernet2/3 switchport access vlan 10 Note Using a separate subnet, and possibly a separate IP address space, may not be an option for some small branch offices due to the IP routing configuration. If the IP routing can handle an additional subnet at the remote branch, you can use Cisco Network Registrar and secondary addressing. Intrachassis Stacking Example The following example shows how to stack GE port 2/0 to GE port 3/0 to form an extended VLAN within one chassis: Router #config terminal Router(config)# interface Gigabit 2/0 Router(config-if)# switchport stacking-link interface Gigabit3/0 The following example shows interchassis stacking being verified between GE port 2/0 and GE port 3/0: Router# show interface gigabit 2/0 GigabitEthernet2/0 is up, line protocol is down Internal Stacking Link Active : Gi2/0 is stacked with Gi3/0 Hardware is Gigabit Ethernet, address is 001b.3f2b.2c24 (bia 001b.3f2b.2c24) MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex mode, link type is force-up, media type is unknown 0 output flow-control is off, input flow-control is off Full-duplex, 1000Mb/s ARP type: ARPA, ARP Timeout 04:00:00 Last input 1d22h, output never, output hang never Last clearing of "show interface" counters 1d22h Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 250707 packets input, 19562597 bytes, 0 no buffer Received 7 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 0 multicast, 0 pause input 0 input packets with dribble condition detected 7469804 packets output, 582910831 bytes, 0 underruns(0/0/0) 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier, 0 pause output 0 output buffer failures, 0 output buffers swapped out 150 Cisco IOS Release 12.2(2)XT, 12.2(8)T, and 12.2(15)ZJ
