Ensure that the crypto map set is applied to the correct interface in the show crypto map domain ipsec command outputs for both switches. Verifying Security Policy Databases Compatibility To verify that the security policy databases (SPDs) are compatible on both switches, follow these steps: Step 1 Issue the show crypto spd domain ipsec command on both switches to display the SPD. The command outputs follow: MDSA# show crypto spd domain ipsec Policy Database for interface:GigabitEthernet7/1, direction:Both # 0: deny udp any port eq 500 any Clear test policies for IKE # 1: deny udp any any port eq 500 Clear test policies for IKE # 2: permit ip 10.10.100.231 255.255.255.255 10.10.100.232 255.255.255.255 # 127: deny ip any any Clear test policy for all other traffic Step 2 MDSC# show crypto spd domain ipsec Policy Database for interface:GigabitEthernet1/2, direction:Both # 0: deny udp any port eq 500 any # 1: deny udp any any port eq 500 # 2: permit ip 10.10.100.232 255.255.255.255 10.10.100.231 255.255.255.255 # 127: deny ip any any Issue the show ipsec internal crypto-accelerator interface gigabitethernet slot/port spd inbound command on both switches to display SPD information from the crypto-accelerator. Note To issue commands with the internal keyword, you must have an account that is a member of the network-admin group. The example command outputs follow: MDSA# show ipsec internal crypto-accelerator interface gigabitethernet 7/1 spd inbound Inbound Policy 0 : Source IP Address :* Destination IP Address :* Source port :500, Destination port :* Protocol UDP Physical port:0/0, Vlan_id:0/0 Action cleartext Inbound Policy 1 : Source IP Address :* Destination IP Address :* Source port :*, Destination port :500 Protocol UDP Physical port:0/0, Vlan_id:0/0 Action cleartext Inbound Policy 2 : Source IP Address :10.10.100.232/255.255.255.255 Destination IP Address :10.10.100.231/255.255.255.255 Source port :*, Destination port :* Protocol * Physical port:0/1, Vlan_id:0/4095 22-8 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05

Chapter 22
Troubleshooting IPsec
IPsec Issues
Step 6
Ensure that the security association (SA) lifetime settings in the
show crypto map domain ipsec
command outputs are large enough to avoid excessive re-keys (the default settings ensure this).
Step 7
Ensure that the crypto map set is applied to the correct interface in the
show crypto map domain ipsec
command outputs for both switches.
Verifying Security Policy Databases Compatibility
To verify that the security policy databases (SPDs) are compatible on both switches, follow these steps:
Step 1
Issue the
show crypto spd domain ipsec
command on both switches to display the SPD. The command
outputs follow:
MDSA#
show crypto spd domain ipsec
Policy Database for interface:GigabitEthernet7/1, direction:Both
#
0:
deny
udp any port eq 500 any
<-----------Clear test policies for IKE
#
1:
deny
udp any any port eq 500
<-----------Clear test policies for IKE
#
2:
permit ip 10.10.100.231 255.255.255.255 10.10.100.232 255.255.255.255
# 127:
deny
ip any any
<------------Clear test policy for all other traffic
MDSC#
show crypto spd domain ipsec
Policy Database for interface:GigabitEthernet1/2, direction:Both
#
0:
deny
udp any port eq 500 any
#
1:
deny
udp any any port eq 500
#
2:
permit ip 10.10.100.232 255.255.255.255 10.10.100.231 255.255.255.255
# 127:
deny
ip any any
Step 2
Issue the
show ipsec internal crypto-accelerator interface gigabitethernet
slot
/
port
spd inbound
command on both switches to display SPD information from the crypto-accelerator.
Note
To issue commands with the
internal
keyword, you must have an account that is a member of the
network-admin group.
The example command outputs follow:
MDSA#
show ipsec internal crypto-accelerator interface gigabitethernet 7/1 spd inbound
