bonding connection for MX and cisco switch catalyst

[Dmen]

Hello, I am using a MX68 and a WS-C2960X. I want to connect 5 LAN ports on MX to 5 sw ports on c2960x with trunk mode and bonding it to achieve a 5Gbps bonded connection.

How can I do it? Thanks

MX does not support LAG/LACP, so you cannot do this. 

It's worth noting the MX68 is rated for 700Mbps, so it won't fully saturate a 1G Ethernet link.

Thanks connorL, so is there any solution to configure a pair of physical ports on both devices as "trunk" ports, enabling VLANs to be carried across the connection? 

[ConnorL]

1 port on both the MX and switch, configured as a trunk with the same required VLAN(s), yes 🙂

No, I mean a solution which can utilize a redundancy protocol like VRRP. There are 2 trunks connections between MX and WS. One can standby for failover functionality.

You can have STP blocking one of the links to your switch.

If you configure the same settings on the two links on the MX, and have spanning-tree enabled on your switch (it should be by default), then your switch should block one of the links.

In case of the active link fails, the other link should then be opened.

Thank you 🙂

As @thomasthomsen has stated, you’ll need a separate link into each switch with loopguard configured on the switch uplinks
