Interesting news I am hearing on Twitter & around the event:
- vPath submitted to IETF
- Cisco VNMC now being called Cisco Prime Controller
My notes, mostly boring stuff that you may not care about:
BRKRST-3114 – The Art of Network Architecture
Denise Donohue starts the session and discusses looking at business requirements.
Russ White talks about cost and modularity:
- BGP is actually control plane virtualization – routing information passing as ships in the night
- State vs stretch (http://packetpushers.net/state-verses-stretch/)
- OODA loop for network security (Observe, Orient, Decide, Act)
- There is no free lunch! & if it is you get what you pay for
Scott Morris talks about selling the design to the business.
BRKSEC-2044 Building an Enterprise Access Control Architecture with ISE
So far it is just a marketing slide deck for ISE. I left early, nothing ground breaking.
BRKDCT-1044 – FCoE for the IP Network Engineer
*I just started taking notes here on everything, literally every slide, just to help me stay awake …
- Storage VDC doesn’t do routing, vlans, etc. Just looks like an MDS stuffed into a 7k.
- FCoE only runs at 10GE and up but iSCSI can run on 1GE.
- TE_Port=Dot1q trunk
- E_Port=Inter switch link
- F_Port=switch side to end node
- N_Port=Node side port
- WWN is like a MAC in that it is burned in but it is not included in the frame
- Switches assign FC_ID addresses to N_ports
- FSPF just like OSPF – uses Dijiska’s algorithm
- Think of zones as ACLs (90% of SAN admin’s job – managing zones)
- FLOGI -> host gets FCID from network -> host receives a list of storage targets in it’s ‘zone’ -> host communicates to the ‘name server’ to get the zone set database -> initiates a PLOGI to the FCIDs it can access
- Inter-VSAN routing – works something like NAT to allow hosts in one VSAN to talk to hosts in another VSAN
- T11 is the standard body for FC
- 802.1 is the standard for FCoE: 802.1Qbb – PFC, 802.1Qaz – DCBx (Configuration Verificaiton) & ETS (Priority Grouping)
- FIP (FCoE Initialization Protocol)
- “Virtual” FC port names: VN_Port, VF_Port,
- NPV mode doesn’t run name server but uses the upstream SAN core that is running in NPIV mode
- FCF (Fiber Channel Forwarder) a logical FC switch inside an FCoE switch
Presentation moves on to FCoE designs, basically the different stages of consolidation.
That’s all the general notes I have. I will be doing a post Cisco Live blog that details notes from in person conversations and further study of slide decks I have collected.
