TP-Link Omada Campus 32-Port 100G Stackable L3 Managed Core Switch

TP-Link Omada Campus 32-Port 100G Stackable L3 Managed Core Switch (S7500-32C) - 5 Years Local Warranty

The S7500-32C is the core switch at the top of TP-Link's Omada campus range: a 1U chassis with 32× 40/100G QSFP28 slots, 6.4 Tbps of switching capacity and the full Layer 3 routing stack — OSPF, BGP, IS-IS, VRF and PIM multicast — needed to sit at the centre of a multi-building network and terminate the 100G uplinks from S7500 aggregation switches below it.

32× 100G QSFP28 and 6.4 Tbps in One Rack Unit

Every one of the 32 ports is a 40/100G QSFP28 slot, giving the S7500-32C 6.4 Tbps of switching capacity and a 2.8 Bpps packet forwarding rate per unit. A 24 MB packet buffer absorbs the bursts that build up where many aggregation links converge, and the MAC address table holds up to 256 K entries. Management is out-of-band through a dedicated RJ45 management port, with RJ45 and USB Type-C console ports and two USB 3.0 ports alongside.

Stack Up to 12 Units Over 100G

Any QSFP28 slot can be used as a stacking port. In standalone mode up to 12 units stack into one logical switch (4 in controller mode), and with all 32 slots set as stacking ports the stacking bandwidth reaches 6.4 Tbps. TP-Link notes that stacking runs only over 100G DAC or 100G QSFP28 modules, not 40G DAC or 40G QSFP — worth planning into the optics order.

Full Layer 3 Routing for the Campus Core

The S7500-32C routes with OSPFv2/v3, BGPv4, IS-ISv4/v6, RIPv1/v2 and RIPng, segments tenants or departments with VRF, and steers traffic with PBR and ECMP while uRPF drops spoofed sources. Route capacity is sized for a large campus: up to 516,096 IPv4 network routes (shared with IPv6), 22,528 host routes, 4,094 L3 interfaces and 45,056 dynamic ARP entries. PIM-SM/DM/SSM and 2,048 IGMP groups carry multicast video and IPTV across routed boundaries.

High Availability From Power Supply to Uplink

Two field-replaceable, hot-swappable power supply bays and five field-replaceable, hot-swappable fans keep the core serviceable without downtime — note the switch ships with one PSM550-AC and the redundant second module is bought separately. M-LAG (with dual-active detection and a peer-link LAG) lets two core switches present one logical uplink to the layer below, while VRRPv2/v3 provides gateway redundancy, ERPS recovers ring topologies quickly and BFD detects link failure in under a second.

Campus Security and Precision Timing

Access control spans 802.1X with RADIUS, RADSEC, MAB and guest VLAN, plus TACACS+ AAA. Dynamic ARP inspection, IP and IPv6 source guard, RA guard, DoS defend, DHCP filtering and IP/IPv6-MAC-port binding (1,024 entries each) protect the control plane, and Secure Boot verifies firmware at start-up. IEEE 1588v2 PTP and 802.1AS support time-sensitive applications that need synchronised clocks across the network.

Centralized Management Through Omada Pro

TP-Link positions the S7500-32C for its Omada Pro platform: the switch is managed centrally from the Omada Pro Cloud-Based, Hardware or Software Controller, with the Omada App and cloud access working through that controller. Zero-Touch Provisioning lets a replacement or new unit be pre-configured in the Omada Pro Cloud-Based Controller and pull its configuration on first boot, so a site does not need an engineer on hand with a console cable. Where a controller is not wanted, the switch is fully manageable on its own through the web GUI, CLI (console or telnet) and SNMPv1/v2c/v3.

Ideal For

Universities, hospitals, large enterprise and government campuses that need a 100G core to collapse multiple S7500 or S6500 aggregation and access stacks, with dual-core M-LAG designs and redundant power. Supplied by SourceIT with local Singapore warranty, GST invoice and project pricing on request.
