I'm currently prepared my CCNP BSCI Certification Exam. I own some old Cisco router devices which I use as a small studdy lab. But a lot of them have only on ethernet connector. I would configure those as router on a stick.
When I try to setup ip address on sub-interface I received the following message : "
Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q, or ISL vLAN."
I try to find how I can configure the interface for ISL encapsulation..... I one documentation on the web I find I should use "encapsulation isl #vlan" command in the sub-interface mode. But in the command listed in the sub-interface mode encapsulation command is not available :
Interface configuration commands:
arp Set arp type (arpa, probe, snap) or timeout
backup Modify backup parameters
bandwidth Set bandwidth informational parameter
bridge-group Transparent bridging interface parameters
carrier-delay Specify delay for interface transitions
cdp CDP interface subcommands
default Set a command to its defaults
delay Specify interface throughput delay
description Interface specific description
exit Exit from interface configuration mode
ip Interface Internet Protocol config commands
llc2 LLC2 Interface Subcommands
mtu Set the interface Maximum Transmission Unit (MTU)
netbios Use a defined NETBIOS access list or enable name-caching
no Negate a command or set its defaults
shutdown Shutdown the selected interface
snapshot Configure snapshot support on the interface
standby Hot standby interface subcommands
timeout Define timeout values for this interface
traffic-shape Enable Traffic Shaping on an Interface or Sub-Interface
on the interface mode I nothing about encapsulation also !!
here is running plate-form :
System returned to ROM by reload
System image file is "flash:c1600-oy-mz.121-6.bin"
also with 2500 Cisco router which cable type I can buy to connected them each other by there serial connector ?? (I know this configuration is most ofter use in lab and is not ofter implemented in production network)
could some help me ??
