300-615 exam

The Objectives of Routing Protocols Port Vlans allowed on trunk The standard and extended ACLs presented in the next sections are numbered ACLs. These represent the classic way of configuring ACLs. Named ACLs are the other way of configuring ACLs and they are presented in a subsequent section. You can disable HTTP access with one simple command: Read through the subnetting and VLSM notes to understand this concept further. It is important! 3.1.bForwarding decision based on route lookup For success in the CCNA exam, and to make it as a new Cisco engineer, you need to understand the following: R1(config)#ip route 192.168.2.0 255.255.255.0 172.16.4.2 Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Sending updates every 30 seconds, next due in 21 seconds Invalid after 180 seconds, holddown 180, flushed after 240 Redistributing: rip 1.Configure an IP address on the two routers facing interfaces and ping across. Exec – shown to the user after the login prompt (used when you want to hide information from unauthorized users) Total Addresses in System : 1 Please take today’s exam at Show the ACLs. Copy and paste into Notepad and make the changes: 1.Add IP addresses to all the interfaces and then ping across the link. I’ve used Ethernet here but you can use a serial link if you wish as in the above topology. Switch#show cdp neighbors Device ID Local Intrfce Holdtme Capability Platform Port ID Switch# The DHCP Pool Configuration mode is also the place where you can configure other DHCP options. In the configuration output above, the following parameters were configured: auto Set trunking mode dynamic negotiation parameter to AUTO SecureStatic address aging : Disabled Security Violation count : 0 Configuring DNS 2.5.c Native VLAN 1004 fddinet-default active Sending CDP packets every 60 seconds Sending a holdtime value of 180 seconds Sending CDPv2 advertisements is enabled Classless protocols use VLSM (i.e., RIPv2 and EIGRP): Remember in an earlier module that the source and destination IP address will never change as the packet traverses towards its final destination. The MAC address, however, will change to permit transport between intermediary devices. This is illustrated in Figure 10.5 below: An err-disabled port might look something like this: The DHCP allocation method can be observed under the Method header with the show ip interface brief command: The service dhcp command is turned on by default, but sometimes it has been manually disabled by a network administrator for some reason. (I’ve seen network administrators call Cisco with urgent routing issues on their network after they entered the no ip routing command on their router – seriously!) This module maps to the following ICND1 syllabus requirements: Configure and verify Layer 2 protocols * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route You can debug RIP on your network generally or drill down to three specific debugs, but bear in mind that this may generate a lot of output, causing either your router or the Telnet session to crash. Dynamic desirable Dynamic auto ------------------------------------------------------------------ password-encryption Encrypt system passwords password-recovery Disable password recovery prompt Enable mode specific prompt Codes: L - local, C - connected, S - static, R - RIP, M - mobile, (C) DOCSIS Cable Device (W) WLAN Access Point, Your choices as a network administrator are to use dynamic routing protocols on your network or static routing, which is where you manually add each route for your network onto each router. The output above is (hopefully) self-explanatory, but you may have a question about the operational mode of the interface. As you can see, it is static access even though it supports multiple VLANs and 802.1Q trunking is allowed. In case you had any doubt that Cisco does not consider these types of ports trunking ports, if you perform the show interfaces trunk general command,300-615 exam, the telephony ports will not show up in that list. That being said, you may need to dig deeper into the multi-VLAN capabilities of the port while troubleshooting.
