I want to upgrade 1841 router with T1 to Cisco 1921-SEC/K9 router . Do i need to purchase an HWIC Module or use one of the two internet GB ports as WAN port to ISP ?
I buy a new Cisco ASA5505-SEC-BUN-K9 firewall which support up to 25 users.I need to upgrade both the ASA version and the ASDM in order to restore my config? any effect if i do the upgrade?
I have a cisco switch 2960S PoE, i'm wondering if i can connect a GLC-SX-MMD on a Cisco 2960S switch at one end and MGBSX1 on a SG300-28 SMB switch at the other end, will the link come up?
