+====== Aruba 6300M Uplink Port Compatibility ======
+===== Summary =====
+During the deployment of a 10Gbps LAG between an Aruba 6300M and an Aruba 6400, the link failed to come up when using standard 10G SFP+ SR modules (e.g., JL260A) in ports 51 and 52. These ports are SFP28 with MACsec capabilities and may reject modules that do not support MACsec.
+After inserting the same SFP+ module into port 50 (SFP56 type, no MACsec), the link came up successfully at 10Gbps.
+This indicates that:
+  * Ports 51 and 52 require MACsec-capable transceivers.
+  * Ports 49 and 50 (SFP56) are fully backward compatible and work reliably with standard 10G SFP+ modules.
+  * It is recommended to use ports 49 and 50 for standard uplinks or non-MACsec LAGs.
+===== Uplink Port Compatibility Table =====
+^ Port       ^ Physical Type ^ Supported Speeds     ^ MACsec Support ^ Compatible Modules           ^ Recommended Use                           ^
+| 1/1/49     | SFP56         | 10G / 25G / 50G       | No             | SFP+, SFP28, SFP56            | Standard uplinks, LAGs, non-secure 10G    |
+| 1/1/50     | SFP56         | 10G / 25G / 50G       | No             | SFP+, SFP28, SFP56            | Standard uplinks, LAGs, non-secure 10G    |
+| 1/1/51     | SFP28         | 10G / 25G             | Yes            | SFP+ MACsec, SFP28 MACsec     | Secure uplinks only (MACsec modules)     |
+| 1/1/52     | SFP28         | 10G / 25G             | Yes            | SFP+ MACsec, SFP28 MACsec     | Secure uplinks only (MACsec modules)     |
+===== SFP/SFP+ Module Compatibility =====
+^ Module     ^ Speed     ^ MACsec Support ^ Compatible Ports ^ Notes                                      ^
+| JL260A     | 10G       | No             | 49, 50           | Standard SFP+ SR module, not for 51/52     |
+| JL261A     | 10G       | No             | 49, 50           | Standard SFP+ LR module                    |
+| JL685A     | 10G       | Yes            | 51, 52           | MACsec-capable SFP+ SR module              |
+| JL640A     | 25G       | Yes            | 51, 52           | SFP28 SR MACsec module                     |
+| JL563A     | 25G       | No             | 49, 50           | SFP28 SR non-MACsec module                 |
+===== Notes =====
+  * If a module is not MACsec-capable, it may not link on ports 51–52.
+  * Use the command ''show macsec summary'' to check MACsec status.
+  * Ensure both ends of a LAG use modules of the same type and speed.
+  * When in doubt, test modules on ports 49 or 50 for basic link validation.
