Hello all,
on a brocade mlx-4 running IronWare : Version 5.4.0fT163, following a crash
(was doing a no ip route under a ip vrf and the box rebooted itself), I am
facing a weird problem.
On a 10G interface i have several customers, each connected in a vlan, with a
vlan interface and a /30 used for the connection. All were working ok before
the crash. Now on some of them i get the following behaviour: i receive a
mac-address all the time, at times there is an arp entry, after some time it is
gone, later it works again (sometime after a cpe reboot, sometime it just
works).
It sounded to me like a cache or an arp limit problem but:
sh ip cache
Total IP and IPVPN Cache Entry Usage on LPs:
Module Host Network Free Total
1 3745 361450 159093 524288
2 4132 361450 158706 524288
3 4996 361450 157842 524288
4 4884 361450 157954 524288
respectively:
#sh default values | i arp
ip arp age:10 min bootp relay max hops:4 ip ttl:64 hops
ip-arp 8192 65536 8192 8192 8192
No
while my arp usage is of 2k (as seen by show arp)
Any ideas what i could look at or what might cause this? Logs do not mention
anything relevant.
Thanks a lot,
Tudor
