Meru opdateringConnection, Marts 2013
Brian Andersen, Systems Engineer
Agenda
• Forskellen på Meru og alle de andre producenter.
• Vores produkt portofølge.
• Hvilken produkter til hvilke typer af krav.
• Eksempler på nogle typiske konfigurationer.
• NSP – Support – Partner Status
• Og forhåbentlig en lang række spørgsmål undervejs.
Kort om WiFi og hvorfor Meru
Radio Physics Review
• Transmission on channels (similar to individual wires)
– Typically multiple channels available at once
• Channel is a shared medium (like a hub)
– Contention for access
– Radio is half-duplex
– Throughput is divided amongst all wireless devices
• Airtime is most precious resource
• Transmission subject to RF interference
WiFi Review – Roaming
Wired LAN (Ethernet)
Channel 1 Channel 6

Station B
WiFi Review – Roaming
• Station A is associated with AP 1 and decides to move towards AP 2.

Dynamic Frequency Selection
Beam Forming
• Sender signalet I retning af klienten. Giver øget dækning ved samme båndbredde
• Fordelen er når klienter befinder sig ved kanten af et AP’s dækning
• Specielt vigtigt for MU-MIMO
• Men men, der er begrænset effekt når AP og klient er tætte (RSSI > -60)

Standard omni-directional antenne
Design af Meru net
Configuration Topology
• Goal is to push wireless service parameters out to access points
• “Profiles” contain sets of configuration parameters
• The arrows show information flow
• Not necessarily a 1-to-1 mapping between profiles
Actually ESS-Interface Tables
Best Practice - kanal valg ,, Virtual Cell ol..
• Check at parent BSSID er ens pr. radio interface
– Via ESS-AP table
• Fra SD 5.3 kan vi på AP1000/AP332 vælge mellem 2 typer af Virtuel Cell:
– VC = shared BSSID (default setting)
– VP = privat BSSID
Check ap kommandoer m.m.
• Show ap-neighbor (4 kolonner L1,L2,L3,L4)
• Show ap-neighbor ap-id interface-id
– Show ap-neighbor 5 2 (ap-id 5 og interface 2 (5Ghz))
• Station dashboard: signal strength
• På radio diagnostics kan noice level ses
• Til sammen giver det SnR. Helst over 20. 25 ved voice
• Radio dashboard: channel utilization
• Packet loss / retry
Backup af controllere
• Show controller
• Copy running-config startup-config
• Copy running-config filnavn
• Filnavn = for eksempel dato-v-SD-version.cfg
• 091112-5096.cfg
• Copy running-config ftp://kunde-091112-5096.cfg
• Så kan vi begynde at opgradere
Opgradering af controllere
• Show controller
• Show flash (viser hvilke software image der er på controller)
• Copy ftp://bruger:pwd@ip-på-ftp/filnavn .
• Filnavn = meru-5.1-90-MC1500-rpm.tar
• Show flash
• Configure terminal -> Auto-ap-upgrade disable
• Upgrade controller 5.1-90 => reboot controller
• Upgrade ap same all
• Configure terminal -> Auto-ap-upgrade enable
Support og fejlsøgning
Support generelt
• http://support.merunetworks.com , også meget gerne på vores partner portal: http://www.merunetworks.com/partners/partners.html
•Mail til [email protected] og der oprettes en ticket.
• Hvis hardware fejl sender support sagen videre til RMA
• Med controller replacement aftale sendes ny controller til kunde, hvorefter kunde sender den defekte retur.Der kommer en ”tom” controller som kunde/partner skal sætte i drift......
• På AP’er er der lifetime warrenty, med sende ind service, efter RMA godkendelse i support.

SD – Radio Dashboard
• Check Retry and Loss
• Check Ambient Channel Noise
• Check Association count
• Check Channel Utilization
• Check Management Overhead
SD - Filtering Packets
• The built-in ethereal sniffer lets you filter packets.
• Syntax:
– -R primitive[[equivalence value]
– No spaces are allowed in filter specification
– Equivalences are: == (equal to), != (not equal to)
• Capture only SIP packets:
– name# capture-packets -R sip
• Capture traffic from an IP address:
– name# capture-packets -R ip.addr==192.168.10.50
• For more complex filtering, capture files to laptop and use Wireshark
