EXTREME EXOS CAMPUS EXAMQUESTIONS WITH CORRECT ANSWERS
Configure VLAN with IP Address - Answer-Configure vlan <name> ipaddress <ip>
Routing Interface - Answer-VLAN that has a configured IP Address
Are all Extreme Switches Routing Capable? - Answer-True
The routing table contains, - Answer-Dynamic and static routes
How to Configure A VLAN with an IP Address? - Answer-configure vlan <name>
ipaddress <ip>
Static Routes - Answer-Entered manually, persist through reboot, and are not
advertised through routing protocols.
Default Route - Answer-A static route that specifies the interface to which the router
forwards packets that do not match any other entry in the routing table.
How to configure a default route? - Answer-configure iproute add default <default
gateway>
How to configure a static route? - Answer-configure iproute add <ip> <nm> <def. gate>
Dynamic Route Types: - Answer-Router Information Protocol (RIP)
Open Shortest Path First (OSPF)
Intermediate System to Intermediate System (IS-IS)
Border Gateway Protocol (BGP)
ICMP Redirects from other routers
Routing Hierarchy - Answer-1. Longest matching network mask
2. Directly attached network interface
3. Static Route
4. ICMP redirect
5. Dynamic Route
6. Directly attached inactive network interface.
View Route Priority - Answer-sh iproute priority
To Change IP route priority - Answer-configure iproute priority <protocol> <priority>
Equal Cost Multi Path (ECMP) Configuration - Answer-Enable iproute sharing
configure iproute sharing max-gateway
,How does ECMP vary per model? - Answer-v22.1 and below - 4
v22.2 and above - 16
Verify the Routing Configuration - Answer-Show vlan
Viewing the routing table - Answer-show iproute
Verifying the IP config - Answer-show ipconfig
Edge License - Answer-IPv4 & IPv6 Unicast Routing Inc. Policy based Routing
BootP Relay
RIP v1/v2, RiPng (IPv6)
Advanced Edge - Answer-BGP Auto-Peering
OSPFv2-Edge & OSPFv3-Edge
PIM-SM-Edge
VRRP
Core License - Answer-OSPFv2 and OSPFv3
BGP3 and MBGP for IPv4 & IPv6
IS-IS for IPv4 & IPv6
PIM-DM
PIM-SM
PIM-SSM
MSDP
Link Aggregation Groups (LAGs) - Answer-Bonding together two or more ethernet ports
into a single virtual port that appears as a single, higher-bandwidth, logical link.
LAG Support - Answer-A link can only be allocated to one LAG at a time
LAG makes multiple links appear as one to STP
LAG is supported on Full-Duplex Ethernet ports
,Physical ports MUST be the same speed
LAG is supported on all Extreme Switches
LAG Configuration Limits (Summit and SummitStacks) - Answer-Static LAG/Health
Check LAG max ports - 8
LACP LAG = 16 (8 members/8 standby)
MAX number of LAGs = 128
LAG Configuration Limits (EXOS Switches) - Answer-X450/X460/X670 - G2s, X770
Static LAG/Health Check LAG max ports - 16
LACP LAG = 64 (32 members/32 standby)
MAX number of LAGs = 128
Dynamic Load Sharing (LACP) - Answer-LACP Dynamically adds or deletes ports to a
LAG based on its link partner state (creates and maintains configuration information for
LAGs)
Health Check Links - Answer-Used to monitor TCP/IP addresses and ports
When connectivity and the port fails, the member link is removed from the LAG.
Static Load Sharing - Answer-Grouping of ports which do not use LACP
Ports have to be manually added or deleted from a LAG
Creating a LAG - Answer-Enable sharing <port> grouping <port list>
Disabling a LAG - Answer-Disable sharing <port> grouping <port list>
LAG Command Qualifiers - Answer-#.. algorithm address-based (uses L2 by default,
L3, or L3_L4)
#.. algorithm port-based (the LAG will use the port-based algorithm)
#.. algorithm custom (LAG will use a custom algorithm)
#.. lacp (enables the LAG for LACP)
#.. health-check (enables tracking of a host IP/TCP port)
, Configuring the LAG Custom Algorithm - Answer-conf sharing address-based custom
ipv4 (configures custom load sharing algorithms for IPv4)
LAG custom algorithm command qualifiers - Answer-#.. L3-and-L4 (Src & Dest IP
addresses & ports)
#.. destination-only (Destination IP Address only)
#.. source-and-destination
#.. source-only (source IP address only)
Configuring a LAG Health Check - Answer-conf sharing health-check member-port
LAG health check command qualifier - Answer-#.. add track-tcp{(Track IP & TCP Port)
#.. tcp-port (TCP port Default=80)
#.. frequency (Default= 10 secs)
#.. miss } (number of misses before a connection loss is reported, default= 3)
Configuring a LAG custom Hashing Algorithm - Answer-conf sharing address-based
custom hash=algorithm
Custom Hashing Algorithm Command Qualifiers - Answer-#.. xor (uses XOR address
hashing)
#.. crc-16 (uses crc-16 address hashing)
#.. crc-32 lower (uses the lower 16 bits of CRC-32)
#.. crc-32 upper (uses the upper 16 bits of CRC-32)
Verifying LAG - Answer-show sharing
Verifying LACP - Answer-Show lacp lag 6
Multi-Switch Link Aggregation (MLAG) - Answer-Combines two or more ports to form a
single logical connection to two devices
MLAG Features - Answer-Dual homing
removes the need for L2 loop prevention
extends regular lag configs for L2 and L3
MLAG Limits - Answer-Peer switches must be of the same family
Can support for more than one MLAG peer
L2 protocols (EAPS/STP) will be configured to not allow the blocking of the ISC
Each switch should be on the same firmware.
