Brocade Switch: "Static Route: Errno(7) Duplicate route entry" On An ICX6610

Have you ever seen this before?
Brocade-6610(config)#ip route 10.20.0.0 255.255.0.0 10.20.0.1
Static Route: Errno(7) Duplicate route entry

Well, first, Errno is not a word.  Second, Im supposed to be able to put in over 2000 static routes if I want to.  However, on the ICX6610, I have to configure it.  The default value for static routes is 64.  Sometimes, I need more than that.  There are some system default values you should be aware of.  Here they are:
Brocade-6610#show default value
sys log buffers:50         mac age time:300 sec       telnet sessions:5

ip arp age:10 min          bootp relay max hops:4     ip ttl:64 hops
ip addr per intf:24

when multicast enabled :
igmp group memb.:260 sec   igmp query:125 sec         hardware drop: enabled

when ospf enabled :
ospf dead:40 sec           ospf hello:10 sec          ospf retrans:5 sec
ospf transit delay:1 sec

when bgp enabled :
bgp local pref.:100        bgp keep alive:60 sec      bgp hold:180 sec
bgp metric:10              bgp local as:1             bgp cluster id:0

So here is how you change that static route limitation of 64 routes:
Brocade-6610(config)#system-max ip-static-route 2048
Reload required.  Please write memory and then reload or power cycle.
Brocade-6610(config)#reload

  1. Have you tried stacking the ICX6610s with other models yet? I have the opportunity to stack a 6610 and a 6450 (meaning they're going in the same rack), and I'm wondering how much headache I'd be signing up for....

    1. I have not done this before, but you can. Check out this link:

  2. Do you know what the 'ip-route' value signifies? Does it literally mean that it can route between over 15000 networks, or is that value instead used per-address? Like a next-hop table.
