I have the following issue with the management interface of an ASA5520 running version 7.0(7).
I'm currently using two contexts in transparent mode.
The management interface is currently assigned to the admin-context and is physically connected to a cat4500 switch in a management Vlan.
The issue is that I have intermitent communication with this IP address from the 4500 and I just can't explain what's going on, the IP address configured in the management port is not repeated in the vlan and the interface vlan in the 4500 is always UP.
This is the configuration I am using in ASA:
access-list 199 extended permit ip any any
mtu gestion 1500
mtu inside 1500
mtu outside 1500
ip address 10.8.129.254 255.255.255.0
arp timeout 14400
access-group 199 in interface gestion
access-group 100 in interface inside
access-group 101 in interface outside
route gestion 0.0.0.0 0.0.0.0 10.8.129.1 1
aaa authentication ssh console LOCAL
http server enable
no snmp-server location
no snmp-server contact
snmp-server enable traps snmp authentication linkup linkdown coldstart
telnet timeout 5
ssh 10.0.0.0 255.0.0.0 gestion
ssh timeout 5
ssh version 1
dhcpd lease 3600
dhcpd ping_timeout 50
As I explained it is possible to log into the ASA using SSH but the connection is dropped at some point. I also need to upgrade the software version but the tftp session is dropped due to lack of conectivity.
Does anybody have a clue regarding the possible solution?
