Automated Management of Large IP Networks
Introduction Context Options
Solution
Conclusions
Today Large IP Networks tend to
be...
Fast growing
Heterogeneous
Difficult to maintain
Difficult to control
So a new concept arises:
“Network Growth Sustainability”
Automated Management of Large IP Networks
Introduction Context Options
Solution
Conclusions
A “Sustainable Growing Network”
would...
Reuse rather than buy new hardware
Recycle rather than enlarge the IP
address pools or maintain inactive
addresses or devices
Reduce the incident handling time

Solution
Conclusions
And answer questions like...
In a full switch stack, can I recycle a port and give
service to a new network jack without having to enlarge
the stack? Which is the port that has been for longer
unused?
Who is the owner of this fake (DHCP) server? Can I
quarantine it from my management console?
Where has been connected this node with a (default
router) duplicate address?
What is the L2 traceroute of a given MAC address?
Who is the owner of this node that 10 days ago
generated a security incident I’m processing now?

Solution
Conclusions
But let me not to spend my time...
On routine tasks like registering a new node in
the network (let the user self service it)
Searching through bridge tables to find in which
port is a problematic MAC address
Following the wires in the wiring closet
Moving stations from one subnet to another
Calling my users to find out who is the owner of
that 10 days ago incident machine

Conclusions
We wanted to apply this philosophy to
our network whose main traits are:
Centralized Network Management…
But not access to user nodes
Multi brand multi generation hardware
+700 Network Switch or Router nodes all
of them SNMP enabled
+14.000 User Network Ports
+420 L2-L2 links
Public and static DHCP served addressing
+10.000 User Network Nodes

Are there “Sustainable” Products in the
Market?
Network Infrastructure oriented (like HP
Openview)
IP Inventory oriented (like ALM)
“NAC” type oriented (like CISCO’s NAC or
Enterasys UPN)
No one met our requirements but…
