Physical networking, bonds & routed IPs
Inspect dedicated-server links and network layers, coordinate switch-side requirements and preserve management access during changes.
How do I check a dedicated server NIC’s link speed and duplex?
Inspect dedicated-server interface state, negotiated speed and duplex, and distinguish physical link capacity from guaranteed application throughput.
Read the answer Physical networking, bonds & routed IPsHow do I check a Linux bond and its LACP partner configuration?
Inspect a dedicated-server Linux bond, member state and LACP evidence, and coordinate the required switch-side aggregation configuration.
Read the answer Physical networking, bonds & routed IPsHow do I verify VLAN tagging on a dedicated server?
Inspect Linux VLAN interfaces and parent links, match provider VLAN assignments, and distinguish tagged trunks from untagged access ports.
Read the answer Physical networking, bonds & routed IPsHow do I inspect a Linux bridge used by virtual machines or containers?
Inspect dedicated-server Linux bridge membership and VLAN filtering, distinguish host and guest addressing, and avoid disrupting the management path.
Read the answer Physical networking, bonds & routed IPsHow do I investigate MTU-related connectivity problems?
Inspect dedicated-server interface MTU and test an authorised path with bounded packets, accounting for tunnels and filtered ICMP responses.
Read the answer Physical networking, bonds & routed IPsHow should I configure additional IPs or a routed subnet on a dedicated server?
Verify provider-assigned dedicated-server addresses, prefixes and routes before planning additional IP configuration or virtual-machine addressing.
Read the answer Physical networking, bonds & routed IPsHow do I change static networking without losing dedicated-server access?
Plan a dedicated-server static-network change with verified console recovery, an approved persistent profile and a supported timed rollback workflow.
Read the answer Physical networking, bonds & routed IPsHow do I investigate packet errors or drops on a physical server NIC?
Read dedicated-server interface and driver counters, measure their growth during an incident, and distinguish physical errors from queue or policy drops.
Read the answer Physical networking, bonds & routed IPsHow do I measure network traffic without running a disruptive speed test?
Measure dedicated-server interface traffic with short samples, distinguish counters from billed usage, and avoid saturating production links.
Read the answer Physical networking, bonds & routed IPsHow do I distinguish provider-edge filtering from a local firewall or application failure?
Separate dedicated-server edge filtering, host firewall and listener failures using local status plus external evidence, without disabling protections.
