I have a (2) virtual chassis's of EX4550's. They've been solid performers for years. (1896 days)
Running 12.2R4.5 as pure Ethernet switches with stp, virtual chassis, lots of ae interfaces. Recently I installed the EX4550-EM-2QSFP with QSFP+-40G-LR4 for dual 40 gig uplinks into my core MX960's, for aggregate ae interfaces link of 80 gbps In doing this I too saw that I had to upgrade to 13.2X50-D10 but I recall that I couldn't find that version on juniper.net so I went with something newer. https://www.juniper.net/documentation/en_US/release-independent/junos/topics /reference/specifications/expansion-module-ex4550.html My plan was to extend my mpls edge into this EX4550 VC I installed 15.1R6-S2.1 I tried to run MPLS L3VPN's in the EX4550 VC, but it's not acting right so I reverted back to pure Ethernet switching in the EX4550 VC and will probably be fine with MPLS edge on the MX960's 15.1R6-S2.1 has been working fine. - Aaron _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
