[ietf83-tech] Can't reach routers from ietf-hotel network

[Bill Fenner]

One of the failure modes that I've consistently experienced through
the week has returned this morning:


dhcp-6704% ping -c 10 130.129.64.1
PING 130.129.64.1 (130.129.64.1): 56 data bytes

--- 130.129.64.1 ping statistics ---
10 packets transmitted, 0 packets received, 100% packet loss
dhcp-6704% ping -c 10 130.129.64.2
PING 130.129.64.2 (130.129.64.2): 56 data bytes

--- 130.129.64.2 ping statistics ---
10 packets transmitted, 0 packets received, 100% packet loss
dhcp-6704% ping -c 10 130.129.64.3
PING 130.129.64.3 (130.129.64.3): 56 data bytes

--- 130.129.64.3 ping statistics ---

I switched to the Concorde wireless and went through the portal and am
getting *great* network.

netdisco tells me that I am on 10.215.6.56, which is attached to
10.215.7.219 port 15 (sadly, that last bit I had to drag out of the
database, since netdisco's device view requires symmetrical CDP to
display where an AP is attached and the APs don't do CDP).  I thought
maybe the switch's MAC address table was full, or something, but the
vlan 2 fdb is way smaller than the vlan 1 fdb.  I don't really have
any other brilliant ideas...
