Historia laboral
05/2015 – 12/2016- Olympics Project Rio de Janeiro Backbone 20 Gbps.
Responsible for setting, configuration and implementing a HIGH AVAILABILITY Backbone
for army network optimization aimed at the Olympics in Rio de Janeiro.
Every technology used CISCO operating ring layer 2, the equipment used were binding
Switch with servers, Cisco 2960, switch the optical ring 3750-x, physical topology with
three stacks, each stack containing 3 switch 3750-x with redundancy source between them.
3900 edge router, OSPF routing protocol used within the ring protocols used were; VLANs
for data traffic via layer 2, distributed by VTP, STP configured PVLAN strategically to
maintain a performance optimization and traffic control aimed at high performance. VTP
Pruning for switches only receive VLANs information used by them so is not a burden
processing with unnecessary information to local and remote access was used SSH with
TACACS + with the permission via ACL Extended with data log sent to each access and
configuration to an FTP server, Any change NVRAM E Running-config also saved on FTP
servers with redundancy.
Optical ring gibs 20, 10 gb etherchannel between the ring and connecting servers running
at 4 Gbps (etherchannel between 4 1Gbps links).
