Hi all, We have 6509 with Dual Sup1A and dual MSFC/PFC. Sup1A is running CatOS ver 5.5(6a) and MSFC is running IOS ver 12.0(3)XE2. These dual engines have been configured for "high availability" and "config redundancy". Multiple vlan interfaces have been configured on the MSFC. HSRP configuration is such that: vlan 10, 20 and 30 have MSFC15 as the primary MSFC and vlan 11, 12 and 13 have MSFC16 as the primary MSFC
vlan 10 has subnet 192.168.10.0, vlan 20 has 192.168.20.0 vlan 11 has subnet 10.0.11.0 subnet and vlan 12 has 10.0.12.0 subnet A printer has been assigned the IP 192.168.10.56 (and thus belongs to vlan10). Users in vlan11 need to access this printer. Users are not aware that 192.168.10.0 subnet exists hence for simplicity we decided to configure a static nat on MSFC15 (the designated MSFC) for the printer ! ip nat inside source static 192.168.10.56 10.0.11.56 ! int vlan 10 ip address 192.168.10.7/24 alt ip address 192.168.10.8/24 standby 10 priority 10 alt standby 10 priority 9 standby 10 ip 192.168.10.1/24 alt standby 10 ip 192.168.10.1/24 ip nat inside ! int vlan 11 ip address 10.0.11.7/24 alt ip address 10.0.11.8/24 standby 11 priority 11 alt standby 11 priority 10 standby 11 ip 10.0.11.1/24 alt standby 11 ip 10.0.11.1/24 ip nat outside ! int vlan 20 ip address 192.168.20.7/24 alt ip address 192.168.20.8/24 standby 20 priority 10 alt standby 20 priority 9 standby 20 ip 192.168.20.1/24 alt standby 20 ip 192.168.20.1/24 ip nat outside ! With this config, users in vlan 11 are able to access 192.168.10.56 however the ping response time is only 50%. ( i.e. even numbered pings to 10.0.11.56 are successful, note here vlan11 has MSFC16 as primary i/f) vlan 20 has also been configured as the "outside" interface for NAT. vlan20 interface has MSFC15 as the primary i/f. Even vlan20 users get 50% ping response if they ping to 10.0.11.56. Any help will be grately appreciated. Thanks & Regards ...
