I use the majority of the 1G ports for VSF.Human carbamoyl phosphate synthetase (CPS1), a 1500-residue multidomain enzyme, catalyzes the first step of ammonia detoxification to urea requiring N-acetyl-L-glutamate (NAG) as essential activator to prevent ammonia/amino acids depletion. Each switch has an SPF+ for storage, 2 for company a and 1 for company b. I have 4 VLANs per switch, storage vlan, company a vlan, company b vlan and MAD vlan. I use the 4 SPF+ on each switches for 10G links to my storage and VMware hosts. I have 3 x 2930f switches that I use as my core switches. Reading this papragraph makes me question my setup. This can play an important part in the design of VSF/VSX as you might not need 8 ports between your member switches - but it depends what your uplinks are and how much east-west traffic there is. The reason for shortest-path forwarding (I just made up that term - not sure what we call it inside Aruba) is it reduces the potential traffic across the VSF/VSX links as traffic will prefer the direct path, not the ISL path. the hashing algorithm kicks in if there is more than one uplink / downlink port on a single member VSF/VSX switch. This means that if there is an upstream / downstream LAG it will take this path first before using the load balancing hashing algorithm. It's interesting to note that with Aruba switches, front plane stacking, such as VSX and VSF uses shortest-path forwarding by default. Switch(config)# vsf vlan-mad Balancing will happen by default over the VSF.

Load Balancing will happen by default over the VSF. If the MAD switch fails, nothing happens if the VSF is working other than MAD stops. You can use an unmanaged switch so that should answer the question :) So, can I use a generic switch to use VLAN MAD? Yes - I would recommend a dedicated VLAN that isn't present on other ports or for other purposes.ĭo I need the MAD VLAN on the MAD switch? Well, you configure the 2930F ports as untagged so you can use any VLAN number you chose on the MAD switch - but I would try to use the same untagged VLAN number if you can configure the switch. VLAN - 2930F only as far as I remember, and it's stupidly simple as (I think) it just uses broadcasts to perform MAD.OOBM - 5400s only (no OOBM port on 2930Fs).Snmp-server community "public" unrestricted Time daylight-time-rule continental-us-and-canada
