# AT1EU-NEXUS-2 — Cisco Nexus 9300 Configuration
## Overview
AT1EU-NEXUS-2 is the **secondary** switch in a vPC pair (role priority 10 — same as primary; tie broken by MAC address). It runs NX-OS 10.3(7) and shares vPC domain 1 with AT1EU-NEXUS-1. The vPC peer-link (Po10) spans Eth1/2728, and out-of-band management (mgmt0 at 192.168.0.2) is used for the vPC peer-keepalive path.
**Key roles of this switch:**
- vPC secondary (role priority 10, tie-broken by system MAC)
- STP root peer (same priorities as NEXUS-1 — `peer-switch` ensures both act as root)
- Layer 3 gateway for Vlan502 (Atom VRF, IP 15.0.2.122/24)
- NTP master (stratum 3)
- Same upstream/storage/compute port-channel topology as NEXUS-1

## Configuration Explanation
### Platform & Global Settings
Identical platform and global settings to NEXUS-1: NX-OS 10.3(7), Jumbo MTU QoS policy (9216 bytes), strict CoPP, AES256-GCM SSH, IP source-route disabled.
### VDC Resource Limits
Same as NEXUS-1.
### Features Enabled
Identical feature set to NEXUS-1.
### Authentication & Access Control
Identical RADIUS configuration, management ACL, and AAA settings to NEXUS-1. VTY exec-timeout is 5 minutes (vs. 0 on NEXUS-1 — worth standardizing).
### NTP
Two additional NTP servers compared to NEXUS-1: `15.32.0.30` (management VRF) and `115.0.0.9` (management VRF). Uses NTP key 125 (vs. key 123 on NEXUS-1). NTP source is Vlan502. Also acts as NTP master stratum 3.
### SNMP
SNMPv3 with SHA/AES-128. Has an additional trap target (15.0.11.80) compared to NEXUS-1. RMON events 15 configured identically.
### VLANs
Substantially the same VLAN database as NEXUS-1 with minor differences: VLAN 103 (Netapp_XFER) and VLAN 130 (SIL_SNAPMIRROR) are not present on NEXUS-2; VLAN 563 (Brace) is present on NEXUS-2 but not NEXUS-1. These discrepancies should be reviewed and aligned.
### Spanning Tree
Identical STP priorities to NEXUS-1. With `peer-switch` enabled in the vPC domain, both switches advertise the same STP bridge ID, making the pair appear as a single root to downstream devices.
### VRF & Routing
Same `Atom` VRF with default route to 15.0.2.254. Vlan502 SVI is at 15.0.2.122/24 (vs. 15.0.2.121 on NEXUS-1).
### vPC Domain
- **Domain:** 1
- **Role Priority:** 10 (same as NEXUS-1; system MAC determines actual secondary role)
- **Peer-link:** Po10 (Eth1/2728), `spanning-tree port type network`
- **Peer-keepalive:** mgmt0, destination 192.168.0.1, source 192.168.0.2
- **Options:** `peer-switch`, `peer-gateway`, `auto-recovery`, 150-second restore delay
- **vPC members:** Po3Po4, Po124Po132 (mirrored from NEXUS-1)
> **Note:** Po124 (9300) uses `switchport trunk allowed vlan 2-4094` on NEXUS-2 (includes VLAN 67) while NEXUS-1 uses `2-66,68-4094` (excludes VLAN 67). This inconsistency should be reviewed.
### Physical Interfaces
- **Breakout mapping:** Ports 1, 5, 9 broken out as 4x25G — same as NEXUS-1.
- **Eth1/1/11/1/2 → Po126 (UCS-B):** The UCS FI cross-connection is intentionally reversed vs NEXUS-1 (NEXUS-1 Eth1/1/11/1/2 go to Po125/UCS-A). This is correct behavior for dual-homed UCS FI connectivity.
- **Eth1/9/11/9/4:** L4 HLCI access ports (Mad Hatter, Javelin, Foxhound, Rock MLS) — note these are L4 VLANs (702, 721, 804, 814) vs. L3 VLANs on NEXUS-1, providing per-switch HLCI layer segregation.
- **Eth1/271/28:** vPC peer-link → Po10
- **Eth1/241/25:** 9300 uplink → Po124
- **Eth1/26:** 500e-X1 → Po3
- **Eth1/23:** NetApp XFER standalone (not in a port-channel)
- **Disabled ports:** Same hardening policy as NEXUS-1
### Telemetry
Same Timba streaming telemetry configuration as NEXUS-1, with a unique node ID. Multiple subscriptions push to 15.0.2.238:443 at 300-second intervals; interface state changes are event-driven (interval 0).
### Logging
Syslog to 15.0.2.146 and 15.0.2.222, both at severity 6. Note NEXUS-1 logs to 15.0.2.146 at severity 2 — this discrepancy should be reviewed.
### Boot
`bootflash:/nxos64-cs.10.3.7.M.bin`
