Routing and switching
VLANs, access ports, trunks, uplinks, EtherChannel, spanning tree, route investigation, and the relationship between the core and access layers.
Cisco consulting in the High Desert
Cisco network engineering, from the access port to the core.
JMB provides Cisco routing and switching support, troubleshooting, and project engineering. Jaen’s experience includes campus networks and larger distributed environments, with work across core, access, and mixed-vendor infrastructure.
Discuss your projectKeep the parts that work. Understand the parts that do not.
An existing Cisco network may need a specific correction rather than a complete replacement. A trunk, uplink, port-security rule, or routing dependency can affect systems far beyond the port where a symptom appears.
Jaen reviews the configuration and the actual traffic path, then develops a plan for the change. Where a refresh is needed, hardware selection, compatibility, staging, migration, and handoff belong in the same project.
Cisco services JMB can provide.
Catalyst and Nexus environments
Configuration review, stack and uplink investigation, vPC-related checks, management access, and documentation of inherited switching.
Port security and segmentation
Investigation of secure-MAC limits, sticky-MAC behavior, private VLANs, and access restrictions where they are part of the existing design.
Replacement and integration
Switch staging, configuration mapping, optics and uplink coordination, cutover planning, and connections to other firewall and server platforms.
Professional Cisco experience.
Campus switching and redundancy
Work included core and uplink validation, time synchronization, unused-port security, VLAN corrections, and campus network documentation.
Campus project summaryDistributed enterprise infrastructure
Experience with core and access switching, private-VLAN and port-security troubleshooting, and the dependencies around server and storage connectivity.
Enterprise project summaryAdditional large Cisco environments
Recent work also includes reviewing switching in another large Cisco environment and planning replacement around the business’s refresh schedule.
Before a Cisco engagement.
Do you require a move to Fortinet?
No. Supporting an existing Cisco installation and replacing it are different decisions. JMB assesses the requirement and existing investment before recommending either.
What should we send with an inquiry?
Start with the switch or router family, the problem or proposed change, and the impact on the business. Configuration files and administrative access can be arranged privately once the scope is understood.
Can you work with our IT staff?
Yes. JMB can take a troubleshooting assignment, assist with a change, or lead the network portion of a larger project, with access and approvals defined.
