Flashcards in CCENT Flashcards Parts 4-6 Deck (37):
1

1-126, 128-191, 192-223, 224-239, 240-255

First octet values of class A, B, C, D, E

2

clock rate *rate-in-bps*

Interface command that sets the speed at which the router supplies a clocking signal, applicable only when the router has a DCE cable installed

3

description *text*

An interface subcommand with which a string of text can be entered in order to document information about the particular interface

4

bandwidth *rate-in-kbps*

Interface command that sets the speed at which the router considers the interface to operate, but does not dictate or control the actual speed. IOS then uses this setting for features that need some information about the speed of the interface (some routing protocols)

5

show ip interfaces brief

Lists a single line of information about each interface

6

show protocols *type number*

Lists information about the listed interface (or all interfaces)

7

show controllers *type number*

Lists many lines of information per interface, or for one interface, for the hardware controller of the interface. On serial interfaces, this command identifies the cable as either a DCE or DTE cable

8

encapsulation dot1q *vlan-id* [native]

A subinterface command that tells the router to use 802.1Q trunking, for a particular VLAN, and with the native keyword, to not encapsulate in a trunking header

9

sdm prefer lanbase-routing

A command on Cisco switches that enables the switch to support IP routing if configured

10

[no] ip routing

Global command that enables (or disables) the routing of IPv4 packets on a router or L3 switch

11

interface vlan *vlan-id*

Global command ton a L3 switch to create a VLAN interface and to enter config mode for that VLAN interface

12

ip route *prefix-mask* {ip-address ; interface-type interface-number} [distance] [permanent]

Global configuration command that creates a static route

13

show ip route

Lists the router's entire routing table

14

show ip route [connected ; static ; rip]

Lists a subset of the IP routing table

15

show ip route *ip-address*

Lists detailed information about the route that a router matches for the listed IP address

16

show vlans

Lists VLAN configuration and statistics for VLAN trunks configured on routers

17

show arp, show ip arp

Lists the router's IPv4 ARP table

18

clear ip arp [ip-address]

Removes all dynamically learned ARP table entries. or the entry for that IP address only

19

router rip

Global command that moves the user into RIP configuration mode

20

network *network-number*

RIP subcommand that lists a classful network number, enabling RIP on all of that router's interfaces in taht calssful network

21

version 2

RIP subcommand that sets the RIP version

22

passive-interface *interface-type* *interface-number*

RIP subcommand that tells RIP to no longer advertise RIP updates on the listed interface

23

passive-interface default

RIP subcommand that changes the default setting on RIP enabled interfaces to be passive instead of not passive

24

*no* auto-summary

RIP subcommand that toggles on and off the autosummarization feature of RIP

25

maximum-paths number

RIP subcommand that sets the number of equal-metric routes for the same subnet that RIP will add to the IP routing table

26

ip address dhcp

Interface subcommand that causes a router to act as a DHCP client, learning the IPv4 address to use on the interface and dynamically learning a default route that uses the DHCP announced default gatewayy address as the next-hop IP address in a static route

27

show ip interface brief

Lists one line per router interface, including the IP address and interface status; an interface must have an IP address and be in an up up state before RIP begins to work on the interface

28

show ip route *rip*

Lists the routing table, including RIP learned outes, and optionally just RIP learned routes

29

show ip protocols

Lists information about the RIP configuration, plus the IP addresses of neighboring RIP routers from which the local router has learned routes

30

show ip rip database

Lists routes for subnets learned from other RIP routers and lists routes for connected subnets for which RIP is enabled on interfaces due to the RIP network command

31

ip dhcp excluded-address *first* *last*

A global command that reserves an inclusive range of addresses, so that the DHCP server function does not lease out these addresses

32

ip dhcp pool *pool-name*

A global command that creates a pool, by name, and moves the user to DHCP server pool config mode

33

network *subnet-id* *mask*

A DHCP pool mode subcommand that defines a network or subnet causing the DHCP server to lease out IP addresses in that subnet

34

default-router *address*

A DHCP pool mode subcommand that defines one or more routers as default routers, with that information passes for clients served by this pool

35

dns-server *address*

A DHCP pool mode subcommand that defines the list of DNS servers that the DHCP server will list for clients served by this pool

36

lease *days* *hours* *minutes* *infinite*

A DHCP pool mode subcommand that sets the length of time for a DHCP lease

37

ip help-address *ip-address*

An interface subcommand that tells the router to notice local subnet broadcasts that use UDP, and then change the source and destination IP address, enabling DHCP servers to sit on a remote subnet
