Hello fma, That's correct. For aggregate interface you would need to explicitly change it through the web-interface by inside the aggregate group. In my lab, I tested it with ae1 having two interfaces 1/7 and 1/8. admin@PA-3050> show system state filter-pretty sw.dev.interface.config (Notice how 1/7 and 1/8 are still at 1500. ) sw.dev.interface.config: { ethernet1/1: { hwaddr: 00:1b:17:89:94:10, mtu: 9192, }, ethernet1/15: { hwaddr: 00:1b:17:89:94:1e, mtu: 9192, }, ethernet1/2: { hwaddr: 00:1b:17:89:94:11, mtu: 9192, }, ethernet1/3: { hwaddr: 00:1b:17:89:94:12, mtu: 9192, }, ethernet1/4: { hwaddr: 00:1b:17:89:94:13, mtu: 9192, }, ethernet1/7: { hwaddr: 00:1b:17:89:94:16, mtu: 1500, }, ethernet1/8: { hwaddr: 00:1b:17:89:94:17, mtu: 1500, }, } MTU settings can be changed by under ae1 > Advanced > Other info > MTU Hope that answers your question! Thanks and regards, Kunal Adak
