I was studying the Blueprints for the 350-001 CCIE written test and a =
thought popped into my head. If everyone who was trying to pass this =
exam would pull together and answer the Blueprint objectives it would =
really benefit everyone.=20
I have answered a couple of the objectives. Lets pass this blueprint =
around tell we get all of the objectives answered.
=20
1.. Cisco Device Operation=20
1.. Commands: show, debug Infrastructure: NVRAM, Flash, Memory & =
CPU, file system, config reg
2.. Operations: file transfers, password recovery,=20
3.. Simple Network Management Protocol (SNMP), accessing devices, =
security (passwords)=20
1.. General Networking Theory=20
1.. OSI model: Layer comparisons, functions
2.. General Routing Concepts: Split horizon, difference between =
switching and routing, summarization, Link State vs. Distance Vector, =
loops, tunneling
3.. Protocol comparisons: Internet Protocol (IP) vs. Internetwork =
Packet Exchange (IPX), Transmission Control Protocol (TCP), User =
Datagram Protocol (UDP), etc.
4.. Standards: 802.x, protocol limitations
5.. Protocol Mechanics: Windowing/Acknowledgements (ACK), =
fragmentation, maximum transmission unit (MTU), handshaking, termination
1.. Bridging & LAN Switching=20
1.. Transparent Bridging: IEEE/DEC spanning tree, translational, =
Configuration Bridging Protocol Data Unit (BPDU), Integrated Routed and =
Bridging (IRB), Concurrent Routing and Bridging (CRB), access lists
2.. Source Route Bridging: Source-route translational bridging =
(SR/TLB), source-route transparent bridging (SRT), data-link switching =
(DLSw), remote source-route bridging (RSRB), access lists
3.. LAN Switching: Trunking, VLAN Trunk Protocol (VTP), inter-switch =
link (ISL), Virtual LANs (VLANS),
4.. Fast Ether Channel (FEC) =
http://www.cisco.com/warp/public/cc/techno/media/lan/ether/channel/tech/f=
etec_wp.htm
5.. Cisco Discovery Protocol (CDP)
6.. Cisco Group Management Protocol (CGMP) When the CGMP-capable =
router receives an IGMP control packet, it creates a CGMP packet that =
contains the request type (either join or leave), the multicast group =
address, and the Media Access Control (MAC) address of the host. The =
router sends the CGMP packet to a well-known address to which all =
Catalyst 5000 series switches listen. When a switch receives the CGMP =
packet, the supervisor engine module interprets the packet and modifies =
the forwarding table automatically CGMP requires Catalyst 5000 series =
software release 2.2 or later and a network connection from the =
Catalyst 5000 series switch to a router running CGMP. By default, CGMP =
is disabled, and no multicast routers are configured. Before you enable =
CGMP on a Catalyst 5000 series switch, you must disable IGMP snooping =
if it is enabled, by entering the set igmp disable command. If you try =
to enable CGMP without first disabling IGMP snooping, an error message =
is generated.
7.. LANE: LAN Emulation Client (LEC) LAN emulation client (LEC)-End =
systems that support LANE, such as network interface =
card(NIC)-connected workstations, LAN switches with ATM uplinks (for =
example, the Catalyst family of switches), and Cisco 7500, 7000, 4500, =
and 4000 series routers that support ATM attachment, all require the =
implementation of a LEC. The LEC emulates an interface to a legacy LAN =
to the higher-level protocols. It performs data forwarding, address =
resolution, and registration of MAC addresses with the LANE server and =
communicates with other LECs via ATM virtual channel connections (VCCs). =
8.. LAN Emulation Server (LES) LAN emulation configuration server =
(LECS)-The LECS maintains a database of ELANs and the ATM addresses of =
the LESs that control the ELANs. It accepts queries from LECs and =
responds with the ATM address of the LES that serves the appropriate =
ELAN/VLAN. This database is defined and maintained by the network =
administrator.
9.. Broadcast and Unknown Server (BUS) Broadcast and unknown server =
(BUS)-The BUS acts as a central point for distributing broadcasts and =
multicasts. ATM is essentially a point-to-point technology without =
"any-to-any"or "broadcast" support. LANE solves this problem by =
centralizing the broadcast support in theBUS. Each LEC must set up a =
Multicast Send VCC to the BUS. The BUS then adds the LEC as a leaf to =
its point-to-multipoint VCC (known as the Multicast Forward VCC). The =
BUS also acts as a multicast server. LANE is defined on ATM adaptation =
layer 5 (AAL5), which specifies a simple trailer to be appended to a =
frame before it is broken into ATMcells. The problem is that there is no =
way to differentiate between ATM cells from different senders when =
multiplexed on a virtual channel. It is assumed that cells received will =
be in sequence, and whe the End of Message (EOM) cell arrives, you =
should just have to reassemble all of the cells that have already =
arrived. The BUS takes the sequence of cells on each Multicast Send VCC =
and reassembles them into frames. When a full frame is received, it is =
queued for sending to all of the LECs on the Multicast Forward VCC. This =
way, all the cells from a particular data frame can be guaranteed to be =
sent in order and not interleaved with cells from any other data frames =
on the point-to-multipoint VCC.
10.. LAN Emulation Configuration Server (LECS) LAN emulation server =
(LES)-The LES provides a central control point for all LECs. LECs =
maintain a Control Direct VCC to the LES to forward registration and =
control information. The LES maintains a point-to-multipoint VCC, known =
as the Control Distribute VCC, to all LECs. The Control Distribute VDD =
is used only to forward control information. As new LECs join the ATM =
ELAN, each LEC is added as a leaf to the control distribute tree.
