BUTTON ON THE FRONT 10. PLUGGING A FEW THINGS IN 1. INTRODUCTION =============== The author will continue to explore the operation of the device while documenting their progress. 2. BATTERY BACKED CLOCK ======================= There is no battery backed clock. A local NTP server may be able to assist. This is not an immediate requirement. The router is intended to be powered 24x7, in the meantime it can be set manually. The ideal deployment would be into a suitably equipped and configured network. In the event of reset, ALL routers pull their time from either a master router, or from a local NTP server. 3. COLD BOOT ============ OK. We're going to switch the thing on! You are already aware of what we've entered into it. So, now after 12-hours of downtime, the device will quite literally be cold booted. Let's see what happens! +-----------------------------------------+ | DESCRIPTION : We Start Here! | | FILENAME : coldboot2.txt | +-----------------------------------------+ You will note that we didn't press anything this time. We didn't try to configure it as before. 4. FAN NOISE ============ The device is exceptionally noisy when placed on an Administrator's desk. There are two real solutions; a) dismantle the device, investigate, replace the fan b) locate the device elsewhere, a data centre rack perhaps 5. [reload] =========== To restart NOW! Switch#reload If you are making configuration changes that may completely lock you out of the router, then with the following command it will reboot automatically. To restart in X minutes; Switch#reload in 5 6. ROUTING ========== Switch(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.0 1 Switch#show ip route 7. SYSTEM RESOURCES =================== Switch#show proc mem Switch#show proc cpu 8. BANDWIDTH THROTTLING ======================= The following commands will limit a client to a set bandwidth. The Cisco term 'Committed Access Rate' is abbreviated to CAR. Create the Access Lists; access-list 100 permit ip any host 192.168.100.100 access-list 100 permit ip host 192.168.100.100 any Apply limiting rules to an interface. If you refer to an non-existant Access List, then the rule will match ALL traffic; rate-limit input access-group 100 512000 1024000 2048000 conform-action transmit exceed-action drop rate-limit output access-group 100 512000 1024000 2048000 conform-action transmit exceed-action drop 9. BUTTON ON THE FRONT ====================== On the front left side of the switch there are two rows of lights. The top row has 2 lights, and the lower row has 4. A diagram will be used to convey this information; +---------------------------------------------------------------------------------- | CISCO SYSTEMS / ------------------------------ | | | | / | /|||\ /|||\ | | | ~~~~~~<|||||||>~~~~~~~~<|||||||>~~~~~~ | | | | | { 1x } { 2x | SYST { X } { X } RPS | | | | | +---------------------------- | { X } { X } { X } { X } | | | | STAT UTIL DUPLX SPEED | | | +--------------+ +------- | | | | | | | | /------------\ | | | | | | | | X | | | | | | | | \------------/ | | | +-----____-----+ +-----__ | MODE | | +---------------------------- | | | +-------------------------------------------------+-+------------------------------ And now to find out what all of those do. SYST = System ------------- The SYST LED lights accordingly; GREEN : Up and Running AMBER : POST failure OFF : Powered Off RPS = Redundant Power Supply ---------------------------- This is effectively a UPS of sorts. There is a low voltage connector on the back of the device, where the blades can be connected to a low voltage power rail. The RPS LED lights accordingly; GREEN : RPS Functional OFF : RPS Not Functional FLASHING : Error STAT = Status ------------- The port LEDs light accordingly; GREEN : Functional OFF : Not Functional FLASHING : Activity UTIL = Utilization ------------------ The port LEDs light accordingly; MORE LIGHTS : More System Load LESS LIGHTS : Less System Load DUPLX = Duplex -------------- The port LEDs light accordingly; GREEN : Full Duplex OFF : Half Duplex SPEED = Speed ------------- The port LEDs light accordingly; GREEN : 100 Mbps OFF : 10 Mbps 10. PLUGGING A FEW THINGS IN ============================ Ports 1,2, and 23 have been populated. The switch seems to have told us something; 00:49:36: %LINK-3-UPDOWN: Interface FastEthernet0/1, changed state to up 00:49:37: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up 00:49:54: %LINK-3-UPDOWN: Interface FastEthernet0/2, changed state to up 00:49:55: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to up OK. There's a command to show us precisely what's happening. [show interfaces] The problem with it is that it outputs so much; +-----------------------------------------+ | DESCRIPTION : File Dump | | FILENAME : showinterfaces1.txt | +-----------------------------------------+ From having examined the file it would appear that our router is functioning correctly. There has to be an easier way to check this though; Switch>show interfaces ?
