N3K-C31108TC-V is a fixed-configuration data center switch for copper server connections, with Layer 2 functionality in its base software configuration. Forty-eight RJ-45 downlinks support 100 Mbps, 1 Gbps or 10 Gbps, while six fixed QSFP28 uplinks support native 40 Gbps or 100 Gbps connections. The Cisco Nexus 3100-V configuration supports migration from Gigabit to 10 Gigabit server networking while retaining copper connectivity. Its rack-mount 1U chassis belongs to the Nexus 3000 family and runs NX-OS rather than an enterprise access-switch software image. The discontinued N3K-C31108PC-V uses SFP+ server ports instead of RJ-45 connections, making server-side connector type the immediate distinction between these siblings. Fixed uplink architecture means the chassis does not require a removable network card to provide its uplink ports.
N3K-C31108TC-V price for new stock is $4,158.00. N3K-C31108TC-V refurb price is $571.73. N3K-C31108TC-V is in stock and available for free next-day delivery. (terms applied)

2160 Gbps switching capacity provides line-rate bandwidth across the interfaces, and 1200 Mpps forwarding defines the maximum packet-processing rate. A 16 MB shared packet buffer accommodates bursts across competing traffic flows without assigning that memory figure to system DRAM. The forwarding hardware supports 288000 MAC address entries and 4096 VLANs for Layer 2 segmentation. N3K-C31108TC-V has 16 GB of system memory and 64 GB of boot flash for its operating environment and image storage. RSTP supports 512 spanning-tree instances, while MSTP supports 64; LACP provides link aggregation, and vPC supports Layer 2 multipathing between separately managed switches. Administration combines the NX-OS CLI with a NETCONF-based XML interface and SNMP versions 1, 2 and 3, with Cisco DCNM available for centralized management. An Ethernet management connection and RS-232 console provide dedicated administrative access. IP routing is not included in the default system software.
N3K-C31108TC-V is offered new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year, with 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested, including rated-speed port links and optics bay recognition, with firmware verified and configurations wiped to factory default; this is separate from Cisco-remanufactured N3K-C31108TC-V-RF. Specify condition, fitted components and software entitlement on the PO before ordering this switch. For enterprise and volume orders, ORM Systems accepts POs, provides Net-30 for government and RMA with advance replacement, and maintains regional stock and RMA across the UK, EU, US and MEA.

When staging a rack before migration, the right-most QSFP uplinks need their intended operating mode selected before production use. Changing between 100/40G and 40G/4x10G operation requires a reboot. Include breakout requirements and the startup configuration in the staging plan before approving the hardware PO.
When multiple data center cabinets require a common sparing configuration, specify airflow with the hardware. NXA-FAN-30CFM-F and NXA-PAC-650W-PE provide port-side exhaust; NXA-FAN-30CFM-B and NXA-PAC-650W-PI provide port-side intake. Standardize the selected direction across fan and power-supply line items in the cabinet bill of materials before placing a volume PO.
When extending an installed Nexus environment, security-maintenance eligibility becomes a procurement constraint rather than just a hardware-condition question. Planned vulnerability and security support ended August 30, 2025. Confirm that organizational security policy permits the intended software lifecycle before authorizing replacement inventory for existing data center racks.
2.5G or 5G copper connections
N3K-C31108TC-V supports 100 Mbps, 1G and 10G copper connections, not 2.5G or 5G. Current replacement N9K-C93108TC-FX3P adds those intermediate speeds while retaining 48 copper ports.
IP routing without additional licensing
N3K-C31108TC-V provides Layer 2 functions in its default software configuration. Routed deployment requires a separate software entitlement; specify an appropriate licensing path rather than an unlicensed chassis alone.

N3K-C31108TC-V identifies the Nexus 31108TC-V copper chassis in the Nexus 3000 family, retaining the TC-V model designation within Nexus 3100-V. Its configuration contains 48 10GBASE-T RJ-45 ports and six QSFP28 uplinks. The complete PID selects the chassis configuration, not an included LAN Enterprise routing entitlement.
Nexus 3100-V supports the NX-OS CLI, RS-232 serial console access, a NETCONF-based XML interface, SNMP versions 1, 2 and 3, and Cisco DCNM management. A dedicated Ethernet management port separates administrative connectivity from server-facing interfaces. Select the required local, programmatic or centralized management workflow before staging the configuration.
N3K-C31108TC-V reached end of sale on August 31, 2022, and its last date of Cisco support is August 31, 2027. Software maintenance ended August 31, 2023, and planned security support ended August 30, 2025. N9K-C93108TC-FX3P is the current replacement for a hardware refresh rather than continued legacy sparing.
ORM Systems offers N3K-C31108TC-V new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's separate platform warranty is 1-year limited hardware coverage, with applicable Cisco support ending August 31, 2027.
N3K-C31108TC-V supports legacy LAN Enterprise N3K-LAN1K9, now end of sale, plus NX-OS Essentials and Advantage subscriptions with three-year minimum terms, or perpetual NX-OS Advantage N3K-AD-XF. N3K-ES-XF-3Y and N3K-AD-XF-3Y identify minimum-term subscriptions. Perpetual licenses remain device-bound; subscription entitlements expire. Smart Licensing requires a Smart Account, independently of the hardware order.
Yes, Nexus 31108TC-V QSFP28 uplinks support 4x10G breakout as well as native 40G and 100G operation. The right-most QSFP ports use selectable 100/40G or 40G/4x10G modes, and changing their mode requires a reboot. Specify breakout connectivity before staging and select link components for the intended operating mode.
Nexus 31108TC-V accepts NXA-PAC-650W-PI or NXA-PAC-650W-PE AC supplies, and NXA-PDC-930W-PI or NXA-PDC-930W-PE DC supplies. The chassis supports two redundant power supplies. AC input is 100-240V; DC input is -40 to -72V. Specify the required power source and port-side intake or exhaust direction on the PO.
N3K-C31108TC-V has 48 10GBASE-T RJ-45 server ports, whereas N3K-C31108PC-V has 48 SFP+ server ports. Both models are discontinued. The copper model suits replacement inventory for copper-connected servers; the SFP+ model suits an existing pluggable-interface configuration. Preserve the installed server-side connector type rather than selecting a spare by port count alone.
N3K-C31108TC-V enables 48 copper server ports, while N3K-C31108TCV-32T starts with 32 enabled copper ports. The remaining 16 ports on the latter require N3K-16T-UPG=. Both models are discontinued. The full-port configuration suits an installed 48-connection requirement; the 32-port configuration matches existing racks that retain the lower activation count.
N9K-C93108TC-FX3P adds 2.5G and 5G copper access speeds that N3K-C31108TC-V does not support. The predecessor supports 100 Mbps, 1G and 10G. N9K-C93108TC-FX3P is the current replacement and retains 48 copper ports, suiting multigigabit refresh requirements; N3K-C31108TC-V suits replacement inventory for an existing 10GBASE-T installation.
