g. Use the show switch vlan command to display the inside and outside VLANs configured on the ASA
and to display the assigned ports. CCNAS-ASA show switch vlan VLAN Name Status Ports ---- -------------------------------- --------- ----------------------------- 1 inside up Et01, Et02, Et03, Et04 Et05, Et06, Et07 2 outside up Et00h. You may also use the command show running-config interface typenumber to display the
configuration for a particular interface from the running-config. CCNAS-ASA show run interface vlan 1 interface Vlan1 nameif inside security-level 100 ip address 192.168.1.1 255.255.255.0 CCNA Security All contents are Copyright © 1992 –2012 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 15 of 35 Step 5: Test connectivity to the ASA. a. Ensure that PC-B has a static IP address of 192.168.1.3 along with subnet mask 255.255.255.0 and default gateway 192.168.1.1 the IP address of ASA VLAN 1 inside interface. b. You should be able to ping from PC-B to the ASA inside interface address and ping from the ASA to PC- B. If the pings fail, troubleshoot the configuration as necessary. CCNAS-ASA ping 192.168.1.3 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.3, timeout is 2 seconds: Success rate is 100 percent 55, round-trip minavgmax = 111 ms c. From PC-B, ping the VLAN 2 outside interface at IP address 209.165.200.226. You should not be able to ping this address. d. From PC-B, telnet to the ASA using address 192.168.1.1. Were you able to make the connection? Why or why not? No. The ASA has not been configured to accept Telnet connections. Step 6: Configure Telnet access to the ASA from the inside network. a. You can configure the ASA to accept Telnet connections from a single host or a range of hosts on the inside network. Configure the ASA to allow Telnet connections from any host on the inside network 192.168.1.024 and set the Telnet timeout to 10 minutes the default is 5 minutes. CCNAS-ASAconfig telnet 192.168.1.0 255.255.255.0 inside CCNAS-ASAconfig telnet timeout 10 b. From PC-B, telnet to the ASA using address 192.168.1.1 to verify the Telnet access. Use the remote access login password cisco to access the ASA CLI prompt. Exit the Telnet session using the quit command. Note: You cannot use Telnet to the lowest security interface outside from the outside unless you use Telnet inside an IPsec tunnel. Telnet is not the preferred remote access tool because of its lack of encryption. In Part 5 of this lab you will configure SSH access from the internal and external network. Step 7: Configure ASDM access to the ASA.a. You can configure the ASA to accept HTTPS connections using the http command. This allows
